All of the Bhaalspawn are dead. This was necessary for the rebirth of Bhaal, which happened in the table top adventure Murder in Baldur’s Gate.
You're comparing board game logic to computer game logic. Don't assume that will apply here. Nothing in Baldur's gate computer games has ever given any indication of ALL children of Bhaal being wiped out. For we know we could be playing as one. .
I think there was a statue of an illithid in the ending cinematics of BG1. Though I'm not quite sure, it has been some time since I've played the game. But you never meet an illithid Bhaalspawn in BG2, so maybe ut remained hidden all this time... until now. :P
Hmm... put a bhallspawn in an illusion of where they can murder? Such things have been done in games before after all. But man, would you have sex with a mindflay- actually, that's a good point. That's not how they reproduce. Which means a mindflayer can't be. Not unless... Do you think Bhall might have done things other then sleep with people to spread his children around? There's a thought... If everyone is so focused on the children yet see a mindflayer that reproduces through tadpoles and turning other races into mindflayers...
Doubt it's the route they'll go with. But it has gotten me thinking. What better way to keep a Bhallspawn of pure anger trapped then to have it in an illusion where they keep fighting?
We also see a clone of Icaris's... complicated love interest? In BG2. This could be implying something. Though what exactly I'm not sure. He was after all obsessed with the power of bhaal.
