I don't know if there's an absolutely officially sanctioned one but it was figured out a while back after a certain amount of head-scratching. ISTR the main confusion was whether D:OS2 occurred before, after or at the same time as Beyond Divinity; plus there seem to have been a few changes to the lore brought about my OS2 as well. I think they wanted it to be a bit more "serious" but I personally prefer the old lore...
Sorry, can't quite remember its whereabouts offhand and I'm in the middle of something right now. eek!
