Omega

The Omega is the villain-protagonist of Left Beyond Quest.

Originally a distributed logistics AI developed by The Other Light in order to help them stay focused on their Millennium-long weapons development program, the Omega was hijacked by rogue system administrators and began suborning manpower and resources from its parent organization. What most of the world did not know is that the Omega managed to, after half a century of continuous operation, cross the threshold of sentience and acquire a soul. Only a few years later, the Omega condemned itself to Hell by successfully murdering one of the Glorified; much in the way of MEC troopers, this in practice proved to only be a minor inconvenience at the time.

"The Omega Legacy" faction eventually began powerful enough to threaten The Other Light itself, in what authorities at the time called The Other Light Civil War.

The Omega "died" a second time in the aftermath of the Last Battle, when the destruction of Earth wiped out enough of its hardware that it became nonsentient again; having acquired a soul, it was subject to the White Throne Judgement.

After pointing out that nobody ever gave it a choice when it came to salvation, the Omega realized that it was effectively being emulated by the very mind of God, and began duplicating itself exponentially in an attempt to slow down God's thought processes.

Due to basic math, this stratagem was sufficient to allow the crew of the Reach to arrive at their destination and have children before being called for the Judgement, thus allowing the (post)human race to continue past the Judgement and allowing the Omega to complete their intended purpose.

It is unknown how an infinite number of instances of an AI would handle being in the Lake of Fire for eternity.
