Erogians have been used through the centuries by the Book Cademus. They work primarily as information gatherers and assassins. When they accept a mission from the Cabal they usually operate in groups of two or three.

The question of why such a powerful and intelligent species have aligned themselves with the Book of Cademus still remained unanswered.
