[Lunaryon]

I necromancer who discovered a way to gain near infinite power by killing himself and at the exact moment of death reanimating his own body... But didn't know that the process opens his mind to entities from beyond. Helps the main character who felt that working with a lesser evil is better then letting the greater evil rein... only that the main villain is controlled by one of those beyond entities and is using the necromancer as an unknowing and unwilling spy.
