Larian Studios Forums Divinity: Original Sin 2 Divinity - Original Sin 2 - General Questions about ending. Major spoilers inside!!!

Finished the game in coop last evening. The ending was a blast. Though I have a few things that I still have questions about. Maybe someone can help me?

1) Why Lucian sent death fog to elves in the first place? There's a lot of bad things started because of this decision but I don't remember any justification for it in the game besides "this sacrifice was needed".

2) Where the hell Lucian went after the final fight? Dallis said that she is too weak, even though she had full hp, but ok. But Lucian just vanished without saying a word. Kinda weird.

3) Why the final showdown stopped after you kill Braccus Rex? The Kraken was there, tons of Dead King's servants as well. And it's not like Dead King was a big fan of Braccus or need him at all. So why should he retreat?

4) I've consumed sources of the paladin Kemm and Sallow Man, but they were still present at the final showdown. Is this a bug or intended? If intended, doesn't it kinda kills the result of your actions?

5) When I've rescued Jahan he told me that he will be my worshiper. But still he wasn't present at the game's ending where all other guys started to worship/buff me. Again, is this a bug of intended?
