Id really like to make this character an old school warlock with all sorts of crazy applications for magic. And the reason I'm aiming for the whole "Artificially lengthened life" thing is because that is the only way (at least in my head) to explain why he is throwing around some really potent magic. And I like the Galatea style of resurrection that would be interesting, it would force him to be a sort of renaissance man as well as a powerful Warlock
