It has already been confirmed that necromancers are in ESO as hostile npc's and that the Mages guild is trying to recover necromantic lore books from the chaos. I am curious if players will be able to interact with some non hostile necromancers and perhaps even join them as a guild.
Mannimarco is one of the main antagonists so perhaps you can join the order of the black worm in some way.
I have always thought that TES should include more evil factions to join and this would be a great opportunity. Maybe at the end of it you could even be rewarded with lichdom.
It would be difficult to make this work seeing as how Mannimarco is a major antagonist but I still think it could work. Learning more of the dark arts would certainly be interesting, especially because I don't think TES has properly incorporated necromancy so far. What do you think?
