The fimir balefiends are the spellcasters and sages of the fimir race. Within fimir society, balefiends seem to have relatively high standing. Every clan has a small cabal of them that serves directly under the tribe's matriarch. They are the only fimir to spend extended periods of time away from their swamp-bound homes. The balefiend's talent for magic can rival that of human and elven wizards, as the fimir learned to use magic from the devils of Baator a long time ago. In addition, the balefiends are gifted with the ability of truesight, further augmenting their spell slinging.
