It's interesting that she has a Bhaal magic circle - I'd only seen that with the Durge before, I thought that might be unique to him.
Also, definitely a doppelganger. Neat. They featured prominently in BG1.
Both Orin and the Dark Urge seem to be avatars of Bhaal which really makes me think their interactions should work differently than if we play as anyone other than the Dark Urge. But no, there was no doubt there would be another avatar of Bhaal besides the dark urge to represent Bhaal in the main story as this is a collaboration between the dead three and they couldn't just have Bhaal missing an avatar for everyone other than the dark urge given Bhaal was the main focus of BG1 and BG2.
*Tavatar I'll see myself out.
Remember the human (This is a forum for a video game):
