Quick background: in World of Warcraft there's a boss called "General Vezax". One way to fight him is to let bits of stuff coalesce into something in the manner of the cartoon character Voltron...
[...] known as the Saronite Animus. While Blizzard maybe simply be using the word animus loosely to suggest a literal spirit, perhaps we should consider the interpretation that the Saronite Animus may be the animus of General Vezax in the Jungian sense -- which would indicate that Vezax is female. Note that Vezax lacks the "proboscis" (to use Damonpike's delicate phrasing) that the other deformed abominations who serve Yogg-Saron seem to have, which would further suggest that Vezax is in fact female. The idea of Jungian complexes being compared to Voltron amuses me to no end -- "I'll form the feelings of inferiority!"
