Originally posted by Link: I'd say Ascension is THE most official mod out there, because it's made by David Gaider, one of the designers of BG2. IIRC it deals with the originally intended ending of the story.

No it doesn't. From the Ascension readme, as written by David Gaider:

The whole thing started on Black Isle's BG2 message boards. A friend of mine, Kevin Dorner (who runs an excellent site called Baldurdash at http://members.home.net/mrkevvy/ ...definitely check it out), had expressed a bit of disappointment at the fact that he had had no choice but to fight the strongest member of the Five, Balthazar. Balthazar was a Lawful Good monk, after all, and wouldn't a charismatic and heroic Lawful Good character be able to maybe talk some sense into him? He suggested that it would have been better to offer a non-fighting alternative or, hey, how about getting Balthazar to fight with you in the final battle? Another poster (alas, I forget who exactly) offered another idea that it would have been a great idea if the Five had been resurrected in the final battle...that it would be cool to face them all at once. And I agreed...that was a very interesting idea.
