The following was taken from the Icarus Foundation’s Research and Archive Department. 

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. 

Reptilian in their true appearance Erogians have the ability to take the form of any creature, human or otherwise, that they have been in direct contact with for more than an hour.  

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