The posts on the page before. And I'm not going to reply to anyone else, pm me if you like. This is like two topics in the same thread

Yes, and I think it would be wise to dispense with the subject of English sovereignty as off-topic for the thread and the forum. Members interested in a counterfactual account of same are referred to Jasper Fforde's Thursday Next series of novels.

Aaaaanyway back on topic

http://www.uesp.net/wiki/Lore:Ancestors_and_the_Dunmer seems to indicate the Telvanni are indeed necromancers but don't practice on other Dunmer.

edit: Perhaps this is why they owned so many slaves? The ones on Vvardenfell didn't appear to own much farm land, and the slaves didn't appear to be doing any sort of labor. Maybe the Telvanni simply fed off their souls.
