Didn't like that the necromancer would be out of place as the only kind of living guy in an undead army and he kind of feels like an underling still because of that. So made something to stand out as a proper leader for an undead horde; a lich. Means the more generic necromancer could then be underlings later if I decide to use more than one at once too.
I used a random generator to get the name mostly.
