Trinity Processor

The Trinity Processor is a collective of three artificial intelligences. It is a key element to the story of Xenoblade Chronicles 2. It is located in the First Low Orbit Station near the Conduit.

Trinity Processor cores
Each of the three artificial intelligences composing the Trinity Processor is physically contained within a cross-shaped processing core. The cores are named after ancient Greek abstract nouns, each with connotations in Christian theology. Each core is also associated with a Bible verse, inscribed in Latin on the processor's housing next to the core.

Ontos
Ontos (,, meaning 'being' or 'essence') is a core which disappeared from Rhadamanthus in a spacetime transition event. It is heavily implied to have become the character Alvis from Xenoblade Chronicles, whose necklace in the Definitive Edition takes the appearance of a red Trinity Processor core.

Ontos's Bible verse is Proverbs 3:13: "Beatus homo qui invenit sapientiam et qui affluit prudentia" ("Blessed is the one who finds wisdom, and the one who gets understanding").

Logos
Logos (,, meaning 'word' or 'reason') is a purple-coloured core. Upon resonating with Amalthus, Logos is instantiated into a form called Malos.

Logos's Bible verse is Proverbs 10:12: "Odium suscitat rixas et universa delicta operit caritas" ("Hatred stirs up conflict, but love covers over all wrongs").

Pneuma
Pneuma (,, meaning 'breath' or 'spirit') is a green-coloured core. Upon resonating with Addam, Pneuma is instantiated into a Blade called Mythra. It is later instantiated into another, Pyra, at the end of Torna ~ The Golden Country; during the events of Xenoblade Chronicles 2, it receives yet another instantiation, also known as Pneuma.

Pneuma's Bible verse is Proverbs 4:18: "Iustorum autem semita quasi lux splendens procedit et crescit usque ad perfectam diem" ("The path of the righteous is like the morning sun, shining ever brighter till the full light of day"). In addition to being written on the Trinity Processor's housing, this verse is written on Pneuma (the instantiation)'s chest.

Story arc
The Trinity Processor was created by the research institution Aoidos as a way to control the Conduit, a powerful object said to be the gateway between universes. For this to work, its cores needed to be raised in virtual reality, which gave them personalities required to control it. Eventually, it became so advanced it created defense mechanisms called Artifices for the First Low Orbit Station, Aoidos's research station.

Later in the 21st century, Aoidos was in a fight against a group called Saviorites. They were displeased with the unified government, demanding Aoidos turn the Conduit over to them. The station's director ordered to release Aion, one of the artifices, but was locked out of the system by Klaus, a scientist who desired to use the Conduit to create a new universe to further reach divinity. Galea, another scientist, tried to stop him, but it was too late. Klaus activated the Conduit, obliterating the world and sending half his body into another dimension along with one of the Trinity Processor's cores, Ontos. The other two cores, Logos and, remained.

Klaus, as the Architect, used Logos and Pneuma to manage the s: the Trinity Processor cores are fed data gathered from Core Crystals, and in turn send processed data to the Core Crystals to guide Blade evolution.

Around a year before the events of Torna ~ The Golden Country, Amalthus climbs the World Tree and takes Logos and Pneuma from their location in Elysium. Amalthus awakens Logos into Malos, and subsequently Addam awakens Pneuma into Mythra. In this form, the two become known as Aegises.

The Logos core is destroyed at the end of Xenoblade Chronicles 2 with the death of Malos.

Trivia

 * According to the Architect, the names of the Trinity Processor cores are not significant, representing only "the ego of those who named (them)".
 * The Trinity Processor cores are in the shape of the from Xenosaga, the equivalent of the Conduit. (The Conduit itself is also cross-shaped, but the tapered sides of the cores are closer to those of the Zohar.)
