Not to be confused with Sentinels.

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 ExcaliburIcon272.pngExcalibur 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 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. All Sentients deal DmgTauSmall64.pngTau damage, alluding to their home system.

History and Overview

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[1], 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. With the use of the Tenno, the Orokin managed to turn the tide of battle.

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

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 GaraIcon272.pngGara, 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 RevenantIcon272.pngRevenant.


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 BasmuA.pngBasmu, crafted with Sentient materials, and the RevenantShotgun.pngPhantasma. The reclusive Quills in particular, with the assistance of the Unum who witnessed GaraIcon272.pngGara'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.pngShedu prove that it is indeed possible to use their technology against themselves, by removing their innate damage resistances. The BallasSword.pngParacesis, 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.pngBattacor. 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.


Sentient Drones

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

Damage Adaptation

Sentients have the ability to adapt up to 4 damage types from attacks: a Sentient's health is gated such that upon its hit points falling below a fixed percentage, it will grant resistance to the damage type it has received the most. The Sentient will adapt to damage once per health gate, at the percentages listed below:

  • First gate: 25% Health lost.
  • Second gate: 45% Health lost.
  • Third gate: 65% Health lost.
  • Fourth gate: 80% Health lost.

Subsequent adaptation will be done in descending order of damage proportion for each health gate. A single Sentient can adapt against a maximum of 4 damage types even if another Sentient transfers their adaptation, and Sentients will still receive full damage from any damage that exceeds their health gate before adapting.

On adapting to a damage type, the color of the glowing core on their chest changes to the corresponding damage type they recently adapted to, along with displaying the icon of said damage type below their health gauge.

The adaptation decreases in effectiveness the more damage types it resists.

  • For the first adaptation, the Sentients will resist the damage type by 90%.
  • For the second adaptation, the Sentients will resist the damage type by 80%.
  • For the third adaptation, the Sentients will resist the damage type by 75%.
  • For the fourth adaptation, the Sentients will resist the damage type by 70%.

Using the Operator's Void Beam, Excalibur UmbraIcon272.pngExcalibur Umbra's RadialHowl130xDark.pngRadial Howl, a rank 40 BallasSword.pngParacesis, or Shedu.pngShedu's pulse on expending all ammo will remove all their damage resistances. They can still regain their resistances, however, the aforementioned abilities and weapons will always be able to remove them.

The Sentients also receive another 40% resistance to the damage type at each adaptation, which stacks multiplicatively with the previously listed ones. These resistances cannot be removed by any of the methods listed above.

The damage gating also prevents Sentients from being killed in one shot, as the maximum percentage of health removable in one instance is:

  • 25% at full health
  • 20% between 75% & 55% max HP
  • 20% between 55% & 35% of max HP
  • 15% between 35% & 20%, after which there is no limit and the Sentients will take damage normally at every instance

For this reason it is highly recommended to use weapons with multishot to multiply the instances of damage dealt per shot like shotguns, weapons equipped with Split Chamber or Barrel Diffusion, or weapons with high fire rate.


  • 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 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. This is further reinforced by the name of the Ceti Lacera.
  • 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 StalkerTwoGreatSword.pngWar, used to be part of Hunhow himself.
