I didn't care much for daedric sorcery. I played this mod: Rise of House Telvanni, along with a bunch of other quest mods, like God Mod, Suran Underground, Horror Mod, Beyond ysgramor. It's quests for the head of Telvanni to increase the power of the house, I don't remember which were particular to the mod, though; you get chambers in sadritha mora council, and I think you can give some quests to your mouth.
