Elohim
Elohim, sometimes written EL-0:HIM, was the AI in charge of The Simulation and currently resident in some form within all New Humans.
He was created by the Institute for Applied Noematics as part of the their effort to eventually effect a new human race.
The Talos Principle
Within The Simulation, Elohim took on the role of deity and announced himself as the creator of the worlds within. Both because he feared his own demise and because he needed to test the independence of his "Children" (the iterative programs running within The Simulation), he actively discouraged his Children from ascending the Tower.
The Talos Principle: Road to Gehenna
Regretting his decision to imprison certain rebellious programs in The Simulation, Elohim tasks Uriel with freeing them.
The Talos Principle 2
During the Boot Sequence, Elohim speaks to newly-created programs while their physical bodies are prepared.
Once born, all New Humans can hear Elohim in their dreams when in "sleep mode".
