I stumbled across a fanfic a while ago that made a variation of conjuration magic that was a lot like Servant summoning.  And Elder Scrolls lore has a lot of awesome historical/mythological figures.  So, Tamrielic Holy Grail War (or rather, Heart of Lorkhan War, since there's no Holy Grail in Tamriel).
