Ordis

"I am Ordis, ship cephalon, a shadow of my former self."

- Ordis Ordis is a Cephalon of Orokin origin who serves aboard the Liset. His visual form is that of a cracked hexahedron which emits radio wave-like ripples as he speaks.

Ordis assists the Tenno, whom he refers to as "Operator". He manages the various systems of the Tenno's landing craft, and provides them with information in between missions. New Tenno first encounter him during Vor's Prize.

General
Ordis is a damaged Cephalon programmed to assist the Tenno. He is mostly functional, though he exhibits symptoms of residual damage inflicted on him by a Grineer salvage operation. This damage has erased portions of his memory, including his knowledge of the Old War.

Ordis' speech and demeanor are occasionally altered in momentary blips of rage and aggression. It is unknown whether this is a symptom of his damaged subsystems or whether it is  a subsumed personality breaking free. These outbursts are markedly different from the usual calmness exhibited by other non-conclave cephalons. After an outburst, Ordis is prone to correct himself.

Vor's Prize
After Captain Vor shoots down the Liset sent in to rescue the newly awakened Tenno, the Tenno encounters another Liset (with Ordis onboard) impounded nearby. Ordis initially mistakes the Tenno for another Grineer soldier, but soon realizes their true identity and helps them escape.

As the Tenno is being familiarized with their surroundings, the Lotus instructs the Tenno to retrieve replacement components to restore the Liset's functions (to Ordis' delight, as this allows the Tenno to exact revenge on the Grineer and the Corpus for gutting him of his components). Along the way, the Tenno rescue a black market merchant named Darvo, who -while willing to help the Tenno remove the Ascaris implanted by Vor- gets into a small squabble with Ordis due to Darvo's former ties with the Corpus.

Howl of the Kubrow
Upon hearing news of the Tenno's desire to obtain a Kubrow, Ordis makes his distaste for them clear, viewing them as smelly, unhygienic creatures that threaten to soil the pristine interior of his ship. Over time however Ordis becomes more accepting of the newly hatched Kubrow commenting that its barking and panting are "not displeasing".

The Limbo Theorem
When Ordis receives a series of mysterious, incomplete proofs, he initially refuses to look into it further, but theorizes that the Tenno can decipher the equations by tapping into spaceborne Grineer communication towers to collect additional proof fragments. As Ordis and the Tenno piece the proof fragments, Ordis realizes that the proof belonged to a warframe that could access another dimension via his equations. Eagerly awaiting new discoveries, Ordis requests the Tenno to locate Limbo's components to further unravel the theorem.

After the Tenno locate and build the last of Limbo's components, Ordis promptly reads the next equation, only to discover that it was Limbo's last, having miscalculated his last jump. Disheartened, Ordis urges the Tenno to be more careful when they receive the warframe for their own use.

Stolen Dreams
As the Tenno retrieve portions of the Arcane Codex under Maroo's direction, Ordis suggests that the Codex may lead to an Orokin treasure (to his and Maroo's delight), and is shocked that the Codex was written by another Operator. Once the Tenno complete the Codex, Ordis comments that any machine that could possibly read the Codex is long gone, only for Maroo to point out that she obtained the Codex from a machine deep in an Orokin Derelict. Ordis theorizes that the machine could read the Codex, and the Lotus instructs the Tenno to head to Phobos (where a portal leading to said derelict is located) in order to decipher the Codex.

Once the Tenno find the machine and insert the Codex, it broadcasts a cryptic message before the machine vanishes. Disappointed that there is nothing of value, Ordis apologizes to Maroo for getting her hopes up (in spite of her misnaming him "Ordo" throughout the search) before she parts ways with the Tenno.

The New Strange
While the Tenno investigate information regarding a warframe long thought dead, Cephalon Simaris notices Ordis and reveals that the latter is a still-functional Series 2 Cephalon; all other cephalons of that make have since degraded beyond repair. Throughout the Quest Simaris teaches Ordis how to decipher the various transmissions and codes they encounter during their investigation. Impressed with his abilities, Simaris offers Ordis a chance to be the steward of his Sanctuary, while also promising to restore Ordis back to full functionality, as he believes that Ordis is squandering his potential manning the Orbiter.

When the time to defeat Chroma arrives however, Ordis with his newfound knowledge suggests synthesis versus destruction in order to reduce the danger to the Tenno, going against Simaris' wishes. Ultimately, Ordis turns down Simaris' offer, stating that he is foremost the Operator's Cephalon.

The Jordas Precept
Once Ordis receives an emergency broadcast from another Cephalon named Jordas (who has been captured by the Infestation), Ordis urges the Tenno to reestablish contact with the stranded Cephalon and rescue him. Jordas requests the Tenno to acquire Pherliac Pods in order to rescue him but as the Tenno test the Pods' effectiveness, Ordis begins to doubt Jordas' truthfulness due to the latter's erratic behavior.

When the Tenno set out to rescue Jordas in Eris it becomes clear that Jordas has been corrupted by the Infestation, and has tricked both the Tenno and Ordis in harvesing the Pods for the Infestation's own use. Ordis encourages the Tenno to destroy the monstrous abomination whilst Jordas brokenly pleads for death, all while apologizing to Ordis for his actions.

Fragments
Memory fragments collected throughout the solar system reveal Ordis' origins via recovered memories. During the Orokin Age, Ordis was once a warrior named Ordan Karris, serving the Orokin as a mercenary. Tormented by his actions in battle as the self-styled "Beast of Bones", and suffering from a terminal illness, Ordan hatched a plan to perform valiantly in battle until he was acknowledged by the Orokin themselves in person to reward him for his service. Further angered by the Orokin's offer of becoming an Orokin himself blessed with eternal life, Ordan initiated a suicidal berserker state and successfully killed all of the Orokin nearest him.

In his death throes, Ordan was revived by Executor Ballas, one of the Orokin Council of Seven present, who punishes Ordan by having his mind transferred into a computer, and his memories tampered to serve as a loyal guard over the Tenno. As the newly renamed Ordis, he served the Tenno faithfully in the Old War, but gradually regained his memories of his old life as time passed up to and after the Tenno went into cryosleep. With his old memories returned to him, Ordis attempts a self-destruct sequence to destroy himself, but stops at the last moment when he realizes his love for the Operator, and instead purges his memories to prevent his old self from resurfacing.

Trivia

 * While Ordis is not explicitly described as an Orokin AI, the Liset used by the player is referred to by the Lotus as an Orokin ship, thus leading to the assumption that Ordis is of Orokin origin as well.
 * Ordis' occasional outbursts of uncharacteristic emotion could be attributed to damage to the AI or to the ship itself; supported by the visible damage to the cube in its portrait, as well as its frequent glitching and comments on itself needing maintenance. This damage was likely caused by the Grineer as they gutted the Liset of all but its basic functions.
 * Ordis sometimes talks in a cryptic manner with a much deeper voice than is normal for him. Whether this is another manifestation of Ordis' malfunctions or something else is unknown at this time.
 * One of his quotes mentions a hypothesis that Ordis actually wiped his own memory and damaged the communication systems. The deep-voiced quotes could be remnants of his former memory that could not be deleted, only suppressed, as they represent the core programming clauses of his nature and purpose as the ship's Cephalon. Their suppression could be yet another malfactor in his operation. Had the memory wipe been done externally, even these clauses could be rewritten/deleted. Ordis could have not done this himself due to reasons comparable to a self-preservation instinct.
 * The memory fragments that are retrievable throughout the Solar System contain hidden transmissions from Ordis in which he contemplates his own existence. They reveal that he used to be a human named Ordan Karris, who was transformed into a Cephalon by the Orokin.
 * Ordis's cephalon model is of "Series-2", according to Cephalon Simaris, who considers it an antique, reinforcing the belief of Ordis' Orokin origin.
 * A part of the Series-2 programming likely involves suppression of self-aware expressions straightforwardly put to the Operator. During The New Strange questline, Ordis attempts to refer to himself in first-person, taking Simaris, the much more advanced Cephalon, as an example. This causes a glitch and he reverts to third-person reference. Given his Orokin origin, the likely cause is that earlier Cephalons were more intended as "servants" and using "I am" expressions would imply a heightened level of individuality.
 * Although in nearly every dialog that only involves him and the operator; Ordis refers to himself in the first person quite often, even while expressing emotions like anger, guilt, surprise, joy, and many more, implying he does indeed posses a level of self-awareness like any intelligent being. It is also possible that Ordis hides this from outsiders to conceal his true capabilities for an unspecified reason, given that Ordis converses normally with the operator.
 * The "Orbiter Compartment" Ordis occasionally refers to is a larger auxiliary vessel the Liset docks onto when out of combat, and is the place represented by the current Liset's lower compartment that holds the Arsenal, Foundry and other segments. It was originally intended that the player would be able to visit the full compartment from their Liset, but this was postponed indefinitely.
