I put it in one thread because they are small questions.
1. Nere Fight
How is it supposed to go?
Before my first fight I had sided with the hired duergar who wanted to steal from Nere. But after I had blown up the stones before the entrance, the dwarfs and Nere immediately turned hostile. I panicked and threw fireballs and hit probably a gnome and perhaps an allied dwarf (but it seemed that all dwarfs were hostile from the start), so they all got hostile and I lost the fight (mainly because of the magma), embarrassing.
In the second trial after the explosions Nere came out and there was a dialog (as I had generally expected) before the fight started because I wanted to save the gnomes and get his head. The fight was boringly easy because this time the treacherous duergar helped me, and the gnomes stayed neutral. Stupid Gale and Wyll this time were a bit more cautious with their spells.
In my current new campaign I did not side with the duergar renegades but just freed Nere. Shortly after the entrance was freed by the explosion, all dwarfs and Nere turned hostile without further ado, there was no dialog. The fight with Nere and all dwarfs is interesting, but I still think the Gith fight is harder and the Ethel fight is more annoying.
Why does Nere get hostile automatically (sometimes)? Does not make sense to attack our party who freed him and is seemingly composed of true souls. Can he read our mind? Is it a bug?
2. Defeat of Ketheric Thorm
The game tells us that Thorm was once defeated by
"a hellbeast" and "maskmen".
I did not find much about it in the Net. I'm no DnD player, do the mentioned forces ring a bell by experienced DnD players? Are the mentioned creatures usually related? Or can that be anything?
