Jero and his astrologer priests had set up a huge Sky God statue in their temple, which they operated through a series of pulleys and glowing crystals. Through that, they were able to force the other Titans to offer up food. A group of heretics led by Talaria eventually invaded the temple, destroying the statue and taking Jero and his priests prisoner. That night, as they sat around a camp fire, Cosmos fell out of the sky, and after Jero claimed this proved the existence of Sky Gods, the priests were freed. When Astrotrain arrived and proclaimed himself king of the gods, the astrologer priests seemed content to go along with it, bar one acolyte who was especially distressed when the Decepticons began messing with the energy crystals.
