Outcasts of Faerûn
Those most likely to worship Fenmarel Mestarine are pariahs and tribes of wild elves struggling to survive in a world hostile to their kind. The clergy of Fenmarel Mestarine offer training in techniques considered underhanded by some, including poisoning, guerilla warfare, and deception.
Members of Fenmarel Mestarine’s clergy pray at dusk, an analogy to when darkness first settles upon the world. Each independent group of worshipers worships and celebrates their god in their own unique way, a representation of the chaotic nature of a profoundly paranoid deity.
Fenmarel Mestarine is a member of the Seldarine, though he refuses to have any contact with them unless absolutely necessary. He is sullen and withdrawn, offering cynicism and distrust to almost any non-elf who he comes across.
