Elementalist Avuun

Elementalist Avuun is a draenei elemental shaman and part of the Hodir encounter in Ulduar. He and his party of excavation team members are trapped inside icicle blocks and must be freed if the raid wants help against Hodir. In 25man version he is replaced by Elementalist Mahfuun.

Speculation
He may possibly be Anchorite Avuun, although the two are two different classes.
