one of the original political prisoners left on the planet Nam Chorios by the Grissmaths, Theras was attuned to the Force. He was contacted by the Spook crystals, which had realized that the drochs used to kill the prisoners were growing in power. The Spooks feared that the drochs would leave Nam Chorios and inflict the galaxy, and used Theras as a sort of prophet. He brought word to the Oldtimers that the drochs could secret themselves on any ship leaving the planet, and that ships of large size could house enough drochs to consume the galaxy. Theras and his followers reworked the planetary defenses to fire on incoming and outgoing ships over a certain mass, in an effort to prevent the drochs from leaving.
