I was going to make a post on this a few days ago, but didn't.Glad to see others noticed. it really is a bit odd. And while yes, Great house Indoril was the most powerful house of the period, we know that Narsis, Kragenmoor, and(I believe) Old Ebonheart(Ebonheart in game as it is the only Ebonheart at the time) belonged to different houses.
@Aenthel The Telvanni thing was most likely to leave content for a later update(something about the Pact about getting Telvanni to join probably)
