To be honest, I always found Necromancy to be the coolest magic. I always wanted to have a necromancy skill in game. The idea of raising an undead army is just so cool.
And you know, tansyuduri, legal necromancers don't use innocents or dug up bodies. The Septim Empire in Cyrodiil donated bodies to sponsored necromancers, usually bandits. Necromancers have asked Gortwag to see if he'd be so kind as to donate some orsimer bodies to study. Plus, for my necro, it's bandits that tend to make up my minions, and as far as every governing body is concerned, save for the altmer and dunmer, that's perfectly legal as they're lawbreakers and would have just been killed anyway.
