Ravnos

The immortal evil.

Teaches that the only one you can trust is yourself.

Ravnos teaches that the only one you can ever truly trust is yourself.  Gain power in whatever form you can and use it.   He is followed by undead, necromancers and many magic users. 

Where his churches are legal, they often serve as morgues or graveyards.  Some teach and store arcane secrets.   It is thought that becoming undead is holy endeavor, and only the worthy are free and have power.
