Erevan Ilesere, The Chameleon
Erevan Ilesere is a fickle, utterly unpredictable deity who can change his appearance at will. He is one of the most fun-loving deities in the multiverse, and he seems incapable of remaining still or concentrating on a single task for any extended period of time. Erevan enjoys causing trouble for its own sake, but his pranks are rarely either helpful or deadly.
