Now I don't know too much about the lore of the TES games, but there was always something that I found odd, especially in oblivion
I'm hoping someone with more knowledge would be able to shed some light on this.
In oblivion, the mages guild is very much against the use of necromancy, and that is shown very much in the mages guild quest line.
HOWEVER... Why is it that the mages guild makes necromancy based spells available for purchase? Is this just a really big oversight on Beth's part, or is there more to this?
