Commander Vyrnnus

A turian who served in the First Contact War and who was hired in 2166 to work at BAaT, training young human teenagers how to use their biotic abilities. Vyrnnus made no secret of his dislike of humans, boasting that "I was at the helm of the dreadnought that killed your father" and driving his trainees hard. The company who hired him, Conatix, kept his involvement quiet from the Alliance public because the memory of the First Contact War was still vivid in people's minds, and the fact a turian was involved in human biotics training wouldn't have been good PR.

Vyrnnus did teach the teenagers how to use their talents, but when he punished one of the trainees by breaking her arm, he was killed, semi-accidentally, by Kaidan Alenko. Vyrnnus' death caused a minor diplomatic stir and future biotic training was transferred to the Alliance military.
