I'm not sure if this is planned to be in Oblivion or not, but I want to create the necromancer's guild. I was really annoyed in Morrowind after reading loads of books about necromancy, and hearing talk of it around towns, yet there was no way to join them. Every single necromancer I found just attacked me on sight So I started a necromancer guild mod for Morrowind which was part of a bigger project, unfortunately though, I never finished it as it became too ambitious.

The guild leader teleported you to a room full of zombies if you annoyed him though . And I did manage to create one spell that summoned a servant zombie, that could follow you and carry things. That one is going to make a come back for sure !
