I tried RP'ing as the drow child of a half-elf <CHARNAME> and Viconia, and BG3 wouldn't be vague enough to let me.
Why does this matter? Because the story in the BG3 would then be a continuation of MY original Bhaalspawn saga playthroughs. I don't want Bhaalpowers, I just want to RP without the game forcing that I am not. Not asking for side-content, just enough mysterious vagueness when the MC is forced to reveal his/her backstory that it doesn't disrupt my head-canon.

In BG2: ToB there are two children possible in the story, a boy named Quayle with Aerie, or an unnamed boy in the epilogue with Viconia. After 1 to 4 generations, the descendants of the Bhaalspawn can be many if not most of the races included so far.

So the suggestion: allow more vague answers when revealing the main character's history and background, if you won't just let me come out and BE the child of the Bhaalspawn.
