This is why it's getting harder to stay with the Lore forum.
I've never heard of a connection between these two Daedra.
This is completely uncalled for. As Hellmouth stated, this is in reference tot he DF god alliances. It would seem YOU are the ignorant one, and I find statements like yours something that is making it harder for ME to stay on the lore forum.
On topic, the god allegiances are basically outdated by now. In DF there were many gods (with more in other regions implied) in a D&D-esque setting. As the TES moved away from D&D-esque settings, the number of true gods diminished and the roles of the remaining gods were cast as more complex, the whole alliance thing became moot.
