So I'm making a new character who is a Mythic Dawn sympathiser, but also a necromancer. I'm wondering if this works lore-wise. Would it be strange for him to be both, or are there any animosities between the two factions? Note that my character would not serve the King of Worms, but the Daedra associated with necromancy i.e Clavicus Vile, Molag Bal etc.

What do you think? Could this work?

Nothing wrong with that. Especially because since Necromancy is based on Conjuration in Skyrim, he could also use his talents to summon some Daedra.

Cool. Come to think of it, wasn't there a Mythic Dawn agent necromancer in Oblivion? Eugal Bellete or whatever his name was?

Necromancers and Dawnies have a lot in common:

Robes

Conjuring

Doing jack-[censored] in caves.

Hehe, true that.

Man, by that logic, I have a lot in common with Necromancers and Dawnies.
