Jacob Keyes taught at the OCS academy as a navigation teacher, until his moving to command of a UNSC frigate.

It was located in the County of Newton in the State of Mare Nubium. The Academy itself was connected to a civilian settlement known as Asimov Center via a series of tunnels and surface tubes.
