The Morag Tong on the other hand gave off the impression of being a vital part of dunmer society. In fact, with Morrowing being in the state it is in, "solutions" to diplomatic... complications would ideally be in the form of assassinations instead of open conflict. Fewer resources and lives lost. I enjoyed the tong quests far more, though being rather repetitive as they were, than the DB missions.
I think back to the Atevi assassins guild from Cherry's "Foreigner" novels. I see certain parallels and doesn't find that as something negative.
