This Dremora was certainly evil, but he wasn't a jerk. He answered my questions, then left.

In my world, summoning creatures from the planes of Oblivion is a studied school of magic, Conjuration. There are some types of conjuration that are looked down upon, such as necromancy, but people are not so prejudiced about its usage as some of the mages here.

Not that it excuses what I did. I...swore off that kind of magic years ago.
