You wouldn't think it's Misho's style, and I wonder if this will seem hypocritical of him in any way; but, as with everything in Exalted, necromancy isn't really evil (Ok, apart from Void Circle). Some of the spells are, certainly, but the same is true of sorcery; necromancy just has a higher proportion of death and destruction, and the first circle of necromancy does have a few honestly "good" spells. As he says himself, he was around when it was first discovered and developed, so he really should know it.

Of course, this means Misho is carrying sorcerous initiations through from his First Age self. HMMM.
