Sentient

The Sentients had won. They had turned our weapons, our technology, against us. The more advanced we became, the greater our losses.

—Orokin 'Warframe' Archive (from  Excalibur Codex)

The Sentients are an artificial race from the Tau System that were the chief enemies of the Orokin during the Old War. Originally suspected to be a truly alien race (whereas the Orokin, Grineer, Corpus and Tenno are all human or trans-human variations originating from Earth, and the Infested are a successive mutation of them), memory imprints provided by the Cephalon Simaris revealed that they were originally created by the Orokin as terraforming machines, to be sent to the Tau System. For this purpose, and against the misgivings of certain Orokin Executors, they were gifted with an extreme degree of adaptability and resilience, bordering on true self-determination. As their name suggests, they inadvertently gained sentience. Coupled with their own innate abilities, they proved to be a formidable threat for the Orokin Empire, almost leading it to its downfall.

History

Sentient remains on Earth, as shown during the Natah quest

Orokin Era

The Detron Crewman's memory imprint seems to suggest that the Sentients were originally developed as terraforming tools bound for the Tau system. The Orokin crafted them with the ability to adapt to any sort of damage that they would encounter as well as the ability to replicate from damaged components, however the Void was "poison" to them, later revealed to interfere with their adaptation and replication. Theoretically, this would have left them stranded in the Tau system once they had finished their purpose.

However, the sentience they had gained also caused them to realize that their creators would lay waste to the Tau system as they did with Earth, and thus they returned to the Origin system to wage war with the Orokin. With their advanced adaptability they were taking over the most sophisticated Orokin technology, and gradually gaining powerful resistances even to the most advanced of Orokin weaponry. In desperation the Orokin utilized the survivors of the Zariman Ten Zero incident, to whom the Void had gifted immense power, to fight back against the Sentient threat. They were trained in the old ways of battle and given conduits that could withstand, channel and amplify their power were created. With the use of the Tenno, the Orokin managed to turn the tide of battle.

Hunhow's ancient body, destroyed and submerged in the depths of Uranus' oceans

However, the Orokin were betrayed by Ballas, who had grown vengeful over the death of his beloved Margulis. Using information provided to him by Ballas, Hunhow sent his daughter Natah, under a human appearance, to serve as a mole within the Origin System. She would destroy the Empire from within and exterminate the Tenno.

Natah completed Hunhow's main objective with the purge of the Orokin but she could not bring herself to kill the Tenno. Instead, Natah chose to adopt them as her own children, as her human predecessor, Margulis, had done before. She hid the Reservoir, the Tenno's only weakness, in the Void, keeping it safe from the retaliation of the Sentient. Denying her old identity, Natah took the name of the flower most beloved by Margulis, the Lotus, and became the Tenno's custodian. The Sentients soon came to believe Natah had been reprogrammed by the Orokin when she encountered her brother Erra on a mission with several Operators, but did not recognize him despite his prodding. This provoked a long-standing disgust Hunhow's family has with Tenno in general, who view Operators as manipulative parasites.

Warframe Era

Excalibur facing an army of Conculysts and Battalysts in the 'Tombs of the Sentient' trailer.

Although the majority of Sentient forces were driven back in what is now called the Old War, the Glass Shards encountered during Saya's Vigil tell of one massive Sentient that managed to land on Earth. This powerful being laid waste to all but one of the cities and Towers: the Tower of the Unum. The tower's defenses held firm with the help of its people and  Gara, who stayed to help defend the tower while other Tenno had scattered. The Sentient, with its power waxing and waning with the dusk and dawn, would besiege the Unum's Tower by nightfall and retreat by morning. Gara would search for the Sentient's resting place during the daylight as the Unum had forbidden her from fighting the Sentient when it was at the height of its power. To aid Gara's search, the Unum gave her refined Temple Kuva to her followers, and instructed them to feed it to the local wildlife, connecting their consciousnesses to her own and allowing the Unum to discover the Sentient's refuge as the animals roamed.

The Unum's plan had unintended consequences however, as when the Sentient captured one of the infused animals for study, it discovered that Kuva could restore its lost ability to replicate. Emboldened by the hope of rebirth, it escalated its nightly attacks as a result. As the Sentient besieged the Unum, Gara chose to confront the threat, carrying a bomb to its core and falling in battle. As the vile Sentient descended upon the mortally wounded Gara, the bomb detonated, devastating the Sentient in the process and ending its threat on the Unum once and for all.

As testament of this final, climactic battle, the Sentient's fossilized wreckage is littered across the Plains of Eidolon, a peculiar landscape with potent and unique resources. The being's dark power still stains the ground, waxing with the fall of darkness and waning at the crack of dawn, altering the environment each night as the Eidolons, its now-mindless fragments, wander the land in an endless search for completeness.

After Gara's sacrifice, the very site of her decisive battle with the Sentient left what the Ostrons now call Gara Toht Lake, but unknown to all but the Unum and her most loyal followers The Quills, the Sentient's main consciousness lay submerged somewhere in the lake, and it would attempt to make itself whole once more when night fell. However, a Warframe known solely as the Warden would arrive, driving the Sentient night after night. This trial would continue until one fateful evening, where the Warden foolishly tried to make contact with the Sentient and was overwhelmed. Discovering that the Sentient was using him as a means to reform itself, the Warden cast himself into the lake to seal it. The time spent as an "anchor" to the Sentient would infuse the Warden with its eldritch energies, transforming him into the  Revenant.

Main article: Category:Sentient

Before The Second Dream events, the Sentients were considered a distant memory by most of the Origin System's population, and even though there are Sentients that survived the Old War, they were few and mostly fragments. After Sentients progressively began to be a threat to the Origin System again, their technology has started to be studied and used by many factions, including the Tenno themselves, a good example being the  Basmu, crafted with Sentient materials, and the  Phantasma. The reclusive Quills in particular, with the assistance of the Unum who witnessed  Gara's final battle, have utilized resources from the Plains of Eidolon to develop modular components for a hand-mounted blaster, which allows select individuals to channel the energies of the Void into more coherent forms for combat. Other weapons directly crafted by salvaging Sentient body parts such as the  Shedu prove that it is indeed possible to use their technology against themselves, by removing their innate damage resistances. The  Paracesis, crafted by using Eidolon Shards, is considered the "Sentient slayer" due to its innate ability to channel void energy, removing their ability to adapt.

Sentient technology as a whole is organic in appearance, emphasizing the use of curves, arches, and symmetry. Even their warships are considered living beings, and are seemingly capable of reconstructing themselves. The average Sentient is formed around a central core of energy which, coupled with their independent development from the rest of the Orokin Empire and its descendants, gives them a suitably "alien" appearance compared to the native technologies of the Origin System. This design philosophy has its drawbacks, as any force capable of ripping a Sentient's "torso" and exposing the core to damage will kill the Sentient easily. Although their ability to replicate from broken components is stunted due to the Void's properties, there's at least one example of a functional weapon created from the remains of a damaged one.

As knowledge of the Sentients has been limited for a very long time, as well as their natural ability to subvert advanced techology, very little progress has been made of developing Sentient-based technology that isn't based on salvaging Sentient remains; Cephalon Simaris has found a means to create artificial copies of Eidolon Shards, though they're nowhere near as potent as actual Shards when it comes to the power they contain. Surprisingly, the Grineer have developed a crude means of containing Sentient energy, which is deployed to troops stationed on the outskirts of Cetus as a means of fending off smaller Eidolons at night. Regardless, the Grineer still err on the side of caution and position their base camps and outposts away from the path of larger Eidolons.

Concerningly, the Corpus are developing their own Sentient-derived projects. One location in the Orb Vallis holds nothing less than a largely intact Conculyst surrounded by several smaller fragments of Sentient devices within a special containment cell, whilst a nearby testing chamber also features a firing range with a  Battacor. Their eventual breakthroughs resulted in a garguantan combat platform whose shields possess the same damage adapation ability that the Sentients have, which combined with other factors makes it all but seemingly invulnerable. Sites within the Corpus Gas City under Alad V's command have also created Amalgams, hybridizing Grineer and Corpus alike with Sentient technology. The Corpus's advancements are stated to "chisel weapons from their bones", implying that they are incorporating Sentient bodies to craft weapons. The most evolved Amalgams, however, can be considered part of the Sentients themselves, and will therefore attack their former faction.

Enemies

Sentient Drones

• Aerolyst
• Battalyst
• Brachiolyst
• Conculyst
• Mimic
• Oculyst

Main article: Aerolyst

Aerolysts are flying Sentient combat drones with the ability to heal their allies. They are immune to harm until the eight canisters surrounding their torsos are destroyed.

Main article: Battalyst

Battalysts are Sentient combat drones. Capable of firing explosive projectiles and unleashing large clusters of omnidirectional lasers, Battalysts specialize in ranged combat. They have the unique ability to "adapt" to their enemy's attacks and gain resistances to damage types, facilitating the need to use multiple damage types in order to take them down.

They are first encountered in The Second Dream quest. They can then be encountered on the Orokin Moon tileset on Lua, spawning in pairs after an Oculyst scans a Tenno at the Orokin Moon tileset. They have also attracted the interest of the Corpus and can be very rarely encountered in Orb Vallis's Enrichment Lab, as well as in the Corpus Gas City tileset on Jupiter within the secret laboratories in test tubes and during the last phase of the Ropalolyst fight. They can mainly be found in Murex ships in Veil Proxima, where they dwell together with other Sentient unities.

Main article: Brachiolyst

Brachiolysts are Sentient enemies normally encountered only on Murex Ships in Veil Proxima. They are also encountered during Sentient invasions during the New War. Unlike most Sentient enemies, they do not adapt to damage, nor do they feature a visible Core on their body.

Main article: Conculyst

Conculysts are Sentient combat drones specialized for melee combat, capable of performing agile, heavy strikes, and forming an offensive whirlwind with their baton-arms alone. They have the unique ability to "adapt" to their enemy's attacks and gain resistances to damage types, facilitating the need to use multiple damage types in order to take them down.

They are first encountered in The Second Dream quest. They can then be encountered on the Orokin Moon tileset on Lua, spawning in pairs after an Oculyst scans a Tenno at the Orokin Moon tileset. They have also attracted the interest of the Corpus and can be very rarely encountered in Orb Vallis's Enrichment Lab, as well as in the Corpus Gas City tileset on Jupiter within the secret laboratories in test tubes and during the last phase of the Ropalolyst fight. They can mainly be found in Murex ships in Veil Proxima, where they dwell together with other Sentient unities.

Main article: Mimic

Mimics are Sentient units which are first encountered in The Sacrifice quest and can later be found on the Murex which occasionally appears in Veil Proxima. They take the form of normal environmental objects to catch enemies off guard.

Main article: Oculyst

Oculysts are mysterious drones that can randomly appear in missions, analyzing and scanning their surroundings. Players will first encounter them in any Uranus mission using Grineer Sealab tileset, but only when a player has a Mastery Rank 2 or above. Scanning an Oculyst for the first time triggers the Natah quest.

Main article: Symbilyst

Symbilysts are Sentient combat drones which excel both in offense with their laser beams and in defence with their shield arm, used to protect themselves from enemy attacks. They can be encountered in Murex Ships that appear in the Veil Proxima on a cycle and on Earth in a Ground Assault during Operation: Scarlet Spear. They can also be found during Archon Hunt missions. They drop parts for the  Shedu.

Main article: Vomvalyst

Eidolon Vomvalysts are spectral Sentient creatures firstly found roaming in the Plains of Eidolon at night. Another Vomvalyst variant, simply called "Vomvalyst", can be encountered on Veil Proxima inside of Murex ships, spawning from unique pedestals, similar to Immunodes. They possess 2 forms: a default physical form and a ghostly energy form to which they switch when they have taken too much damage.

Main article: Ionyx

Ionyx is a heavy Sentient fighter that is first introduced during Operation: Scarlet Spear. These briefly appear during Railjack portions of The New War.

Main article: Murex

Murex, formerly known as Sentient Anomalies, is both a Sentient Tile Set and  Sentient warships introduced in Update 27.0 (2019-12-13) which acts as a Point-of-Interest and is encountered in Veil Proxima missions on Empyrean and Operation: Scarlet Spear. They can also be encountered in Break Narmer, labled as a Prison Break mission. The player instead controls Kahl-175, and raids a Murex in search of any prisoners.

It is a Sentient troop transport ship notable for its alien interior and incredible size. Inside of it almost all existing Sentient units can be encountered.

The inside of a Murex

Murex ships are relevant to three game modes: Skirmish Railjack missions, Murex Raid missions, and the Prison Break mission of Break Narmer. <onlyinclude>

Skirmish

A Murex will occupy a Grineer-controlled node on the Veil for 30 minutes, indicated by a red flashing  Sentient symbol, after which it will rotate to a different node. The Murex will not appear in Void Storm missions.

While active, a Murex will constitute a mission objective in the Railjack mission (similar to a Pulse Turbine or Shipkiller Platform). Cephalon Cy will request that the Tenno investigate the Sentient presence in the area at the beginning of the mission. Once the Tenno enter the Murex, Cephalon Cy instructs them to "sterilize" it of Sentient life as a means to prevent Grineer exploitation. Once 20 Sentient enemies are destroyed, Cy deems the objective complete.

The red crystal

The Tile Set features high level Sentient enemies, and is the first area to house the Brachiolyst and Symbilyst. After killing 20 Sentient enemies in this Point of Interest, all players within the squad will receive an Anomaly Shard, which can be traded to Little Duck for exotic Sentient goods, such as the Tenebrous Ephemera and Sentient Ship Captura scenes.

Originally, destroying a red crystal within the Murex, which required the  Paracesis, would start the Erra Quest. This is no longer accurate and the Quest can be accessed directly from the Codex upon completion of the Chimera Prologue Quest.

Murex Raid

Main article: Operation: Scarlet Spear

The Murex Raid mission has two distinct phases: transporting the OpLink Satellite and deploying Kill Codes.

The mission starts with the Railjack carrying an OpLink Satellite, which must be brought in front of the Murex. While carrying the satellite, the forward turrets are disabled, though Munitions may still be fired. Sentient Gyrix and Ionyx will attempt to destroy the satellite, along with Splintrix delivering boarding parties. The most notable of these troops is the Anu Mantalysts which will deposit Anu Interference Drones to disrupt the Railjack's systems, preventing the use of Tactical and Battle Avionics, and reduce its speed. Later in the mission, Grineer Exo fighters and crewships will spawn. Once the satellite has been delivered, it will become invulnerable and players no longer need to defend it.

The squad must then board the Murex and place their OpLinks, which will upload Kill Codes that are obtained and automatically transmitted by the Ground Assault teams. 9 Kill Codes are needed for Murex Raid players to successfully fend off a Murex ship. Sentient forces will come in waves to attempt to destroy the OpLinks.

Players may extract at any time by using the Railjack's navigation terminal. Up to a maximum of 5 Murex can be fended off in a single run. If the Satellite or all OpLinks are destroyed after fending off one Murex, players cannot continue uploading and are forced to extract.

Prison Break

Main article: Break Narmer

Kahl, you know how you asked me to let you know when that prison Murex came back? Well, it's back. If you really want to do this, call me.

—In-Game Description

Boarding a prison Murex emerging above Deimos, Kahl seeks to rescue any captives onboard.

This mission is largely the same as in the Veilbreaker quest: Kahl fights off Sentient forces, stands in dissipation fields to free brothers, orders brothers to destroy debris and Immunodes as needed, frees a Tusk Bolkor and then crash-lands it while acquiring its  Grattler, and reach the Railjack at evacuation. Beware that any missed objectives may not be returned to after boarding the Bolkor.

As the group nears extraction, Daughter intercepts an abnormal Grineer signal, stating that "it's as if he was connected to a Sentient mind" before the Narmer Empire, to which Kahl adds that he heard of that one. After Kahl and the captives reach the hangar, Daughter expresses genuine shock on the Grineer being still alive, despite his mental trauma, Amalgam rejection, and chemical hypersaturation. Kahl states that he will do what must be done as the Grineer was suffering, but Daughter tells him that he cannot save everyone.

Kahl agrees and instead plans to kill the Grineer, which is then revealed to be none other than the Wolf of Saturn Six, now under Narmer service. The Wolf focuses his attacks solely on Kahl, using melee, long-ranged charges, ground shockwaves, and throwing his hammer; stay moving at all times and hover as needed to avoid the danger. After ending the Wolf's suffering, Kahl and the captives board the Railjack and escape.

Lore

Murex are Sentient vessels created as a mobile settlement or outpost of sorts. They may also be used as places of worship, as the Murex are filled with prayer altars and statues. The Murex have suffered damage due to the many eons spent drifting in space. However, they are able to rebuild themselves by using repurposed debris, similar to the Sentient Mothership, Praghasa.

Sentient prayer altar

Sentient coffin

Physiology

The Murex are not mere spaceships, instead they are massive Sentient organisms. Their various chambers and rooms are connected via orifice-like doors, that bear a similar resemblance to a digestive tract or vocal cords. It's immune system also appears as various hazardous defenses, such as Immunodes and Occular Walls.

Additionally, numerous pools of Sentient biofluid can be found scattered throughout the body of the Murex. The exact function of these pits are unknown, however, numerous Sentients can be seen being formed within them. From this, it can be inferred that these pools may act as birthing pits for smaller Sentients.

Features

Immunode concept

Immunode Altars

Immunodes are altar-like constructs with a glowing orb of Sentient biofluid in the middle. They can occasionally spawn within the tileset, granting nearby Sentients temporary damage immunity. The immunity can be removed by destroying the Immunode, and only one Sentient at a time can receive the damage immunity.

Spawn Altar concept

Vomvalysts Spawn Altars

These pod-like altars have a similar appearance to the Immunodes altars. Upon being approached by players, the main part will turn invisible, and release a Vomvalyst drone.

Each altar will only release one Vomvalyst, after which the altar will remain transparent for the rest of the mission.

Red Death Orbs

In some tilesets, there are floating red energy orbs that slowly travel around the room. They have a preset path, however they will attack the player if they get too close, seemingly bypassing armor with  True damage. These orbs can only be attacked with the Operator Void Beam, but has no health bar and is therefore invincible. It also bypasses  Limbo's Rift Plane. However, going into Operator Void Mode does make the player immune to its attacks.

Medusalyst Towers

Medusalyst Towers are stationary Sentient constructs that act as turrets. Upon spotting the player, they will lock on, and begin to slowly fire energy blasts.

Ocular Walls

Scattered around the Murex are swarms of Sentient-like eyes that reside on the surface of the walls. Upon detecting a player, they will begin to glow red. If the player gets too close, the orbs will detach themselves from the wall and detonate, staggering the player while causing a small Blast proc.

Transport Conduits

The entrance of these gate-like conduits will form when the player gets close to it, allowing it to be entered by walking inside. Doing so will cause the player to go through a tunnel-like pathway at high-speeds, bringing them to the next section of the map. They can be re-entered from both sides.

Sentient "Loot Fairies" concept

Sentient Resource Creatures

Instead of normal Resources containers, Murex ships contain smaller stationary Sentient Membroids that act as resource containers.

These Sentients appear as sack-like creatures with a single horn on their head. They are able to store various resources in their bulbous abdomen, which splits open when they are struck.

Secret Rooms

Within the Murex, certain walls can be destroyed with  Void damage, revealing small rooms with loot inside. They are distinguished by having a weaker and thinner appearance than the surrounding wall. Bug: clients can use any damage type to break the wall.

• Some doors are resistant to damage. Instead, use Void damage repeatedly to open them. They will close quickly if the number of attacks used was insufficient, and also will close automatically after some time.
  • For fast runs, any AOE damage abilities/weapons with enough range may break containers inside and can be collected remotely with the use of  Vacuum/ Fetch

Trivia

• Murex is a genus of medium to large sized predatory tropical sea snails. Imperial purple is a secretion produced by several species in the family Muricidae, originally known by the name Murex.

Splintrix are Sentient boarding capsules in Empyrean. They are first introduced during Operation: Scarlet Spear. Murex ships will launch a Splintrix at the Railjack if it gets close to it. If it hits the Railjack, the boarding party that will spawn will consist of Anu Mantalysts, Anu Pyrolysts, Conculysts, Battalysts, and Symbilysts.

Bosses

• Teralyst
• Gantulyst
• Hydrolyst
• Ropalolyst
• Condrix

Main article: Teralyst

The Eidolon Teralyst is a gigantic spectral Sentient Eidolon creature that can be found aimlessly roaming around the Plains of Eidolon at night, acting as one of the Grand Bosses of the landscape. This is the first of the 3-night bosses of Plains of Eidolon, followed by Eidolon Gantulyst and then Eidolon Hydrolyst.

The Eidolons are remnants of a massive Sentient that was defeated in a battle against the Tenno during the Old War, whose remains now wander the plains perpetually searching for their lost components. These fragments are, however, still formidable creatures armed with powerful attacks and near-impenetrable defenses, and are hostile to both Tenno and Grineer alike.

It is important to note players that have not unlocked Transference from The War Within won't have any means to properly fight the Sentient.

Main article: Gantulyst

The Eidolon Gantulyst is an enormous spectral Sentient Eidolon creature that can be summoned on the Plains of Eidolon at night, acting as one of the Grand Bosses of the landscape. This is the second of the 3 night bosses of Plains of Eidolon, preceded by Eidolon Teralyst and followed by Eidolon Hydrolyst. Much larger than the preceding Eidolon Teralyst, this one has replaced its right arm with an elongated boulder, and its massive weight creates shockwaves with every step.

All Eidolons are remnants of a Sentient that was defeated in a battle against the Tenno during the Old War, whose remains now wander the plains perpetually searching for their lost components. These fragments are, however, still formidable creatures armed with powerful attacks and near-impenetrable defenses, and are hostile to both Tenno and Grineer alike.

It is important to note players that have not unlocked Transference from The War Within won't have any means to properly fight the Eidolon Gantulyst.

Main article: Hydrolyst

The Eidolon Hydrolyst is a titanic spectral Sentient Eidolon creature that can be summoned on the Plains of Eidolon at night, acting as one of the Grand Bosses of the landscape. This is the third and final of the 3 night bosses of Plains of Eidolon, preceded by Eidolon Teralyst and Eidolon Gantulyst. This one is large enough to wield the landing strut of an ancient spacecraft as a weapon, and its arcane energies create localized storm systems wherever it surfaces.

All Eidolons are remnants of a Sentient that was defeated in a battle against the Tenno during the Old War, whose remains now wander the plains perpetually searching for their lost components. These fragments are, however, still formidable creatures armed with powerful attacks and near-impenetrable defenses, and are hostile to both Tenno and Grineer alike.

It is important to note players that have not unlocked Transference from The War Within won't have any means to properly fight the Eidolon Hydrolyst.

Main article: Ropalolyst

The Ropalolyst is a gigantic bird-like Sentient boss capable of flight. It can be found in the Remastered Corpus Gas City on its own Assassination node on Jupiter, requiring players to have completed Chimera Prologue to battle it. It was dispatched by the Sentients to ensure Alad V does not double-cross their "partnership", much to his displeasure.

After defeating the Ropalolyst, the player will receive  Wisp component blueprints and an Amalgam mod from five possible.

Main article: Condrix

Condrix is a Sentient dropship that was introduced during Operation: Scarlet Spear in the Ground Assault mission. They are responsible for transporting and deploying Sentient troops such as Aerolysts, Symbilysts, Conculysts, Battalysts, and Brachiolysts on planets.

Trivia

• Across the various sources and legends mentioning them, the Sentients are, in multiple cases, referred to as having multiple bodies, heads, voices and pairs of eyes. This suggests that a singular "Sentient" is best understood as a single consciousness or guiding mind, inhabiting and controlling multitudes of bodies and platforms with limited independence. This could explain how, even though Hunhow's body was destroyed in the Old War, fragments of him remain, housing his mind so that he is not truly dead.
• Likewise, in the case of the Sentient of the Eidolon Plains, the destruction of the central consciousness lays waste to its various bodies. As the main consciousness was destroyed by Gara, the remaining fragments, the Eidolons, are little more than mindless animals.
• Although the Sentients were mentioned occasionally in earlier builds of the game, it wasn't until Update 17.0 (2015-07-31) where more detailed information about them was revealed.
• While it's never specified which Tau system that the Sentients were destined to go, the most likely candidate would be the Tau Ceti system, as it is a major candidate for extraterrestrial life to develop and possibly thrive, making it a reasonable choice for colonization.
• One of the earlier Sentinel Cosmetics is called the "Hunhow Sentinel Mask" and not only does it share Hunhow's name, but its overall design is similar to the faces of the Battalyst and the Conculyst. It remains to be seen if this was a deliberate piece of foreshadowing however.
• Hunhow refers to the Sentient enemies as his "Fragments", implying they, like the sword  War, used to be part of Hunhow himself.
