Blood in Baldur's Gate happened before abdal died right?
I think the Dark Urge is a Bhaal spawn, they get abducted and spend the next 15 years in the Astral plain with the mindflayers. As they technically arn on Torill Bhaal gets to reincarnate/make an avatar, but is missing the bit of himself that was in the urge.
The Urge seems to be the pure unbridled bloodlust of Bhaal while Orin is more of the sneaky stealthy assasin.
