Kir-lanan
Kir-lanan are a race of gargoyle-like humanoids originally from some other world who were stranded in the Forgotten Realms by some side effect of the Time of Troubles. Because of this, they are super pissed off at the gods of Toril, and seek to destroy them... unfortunately, their plan for doing so consists of starving them to death by eradicating all of their worshippers, which will basically requires the total genocide of every sapient race on Toril.
