True, but if the sigils (which are probably the most powerful stuff he's ever done) are anything to go by, I suppose he might also be an abjurer.
Familicide doesn't kill through disintegration, though, so I guess today's lesson is that if you must be a dragon, try to be open-minded about it.Heh. In that case, though, the young black dragon would have needed at least a Resurrection even if his ashes hadn't dissolved into the swamp. Those scrolls probably aren't that easy to get and True Res must be nigh-impossible even for an ancient black dragon.
