First time I did this quest I paid no heed to the contents of the books, I grabbed them and left. Second time through I decided to read them. Obviously this guy is a necromancer, but I was not expecting him to be a necrophiliac. The journals do not come out and say it directly, but its rather obvious. Then I got to thinking, how many other necromancer's take their corpse obsession to that level-yuck!
I feel the need to jump in a bathtub, rock back and forth and say over and over again "Must get clean."
