1 - Black Mountain Clan
Or what remains of it. You can talk to Grenjar Silver Hammer and the rest of the clan if you want, but nothing much will come of it.
2 - Teleporter to Kerghan
As soon as you enter Kerghan's inner sanctum, you'll start a conversation with him, and you'll learn that he prefers death to life and plans to return to Arcanum to kill everything. You'll have three ways to deal with Kerghan:
a) Help Kerghan. Kerghan will ask you to kill Arronax, Gorgoth, Kraka-tur and the Bane of Kree. If you agree, all the good members of your party (like Virgil and Raven) will turn against you and attack. Sometimes this attack will trigger Kerghan (and his lord's slaves) into attacking you as well, so save before trying. Once you do everything Kerghan wants and return to him, the game will end.
b) Talk Kerghan out of his plan. For this case you'll need to have Arronax in your party, and you'll need to select the dialogue option, "An interesting point of view. I can see the merit it holds." (You'll get the option almost right after the cut-scene.) When Arronax objects, whisper to him that you have a plan, and then try to convince Kerghan that not all souls are in pain. If you keep saying things Kerghan agrees with, then eventually you'll get the option of using the Vendigroth Device on him, to give him a final, irrevocable death. Then you'll get to see the ending cinematic and find out what happened to the various people and places you visited during the game.
c) Attack Kerghan. Just say disagreeable things or demand to fight him, and he'll oblige you. Kerghan has lots of hit points, and a few lord's slaves will appear to help him out, but eventually you should be able to wear him down. When he only has about 10% hit points left, he'll retreat into his shell, and that's when you should use the Vendigroth Device on him to kill him. Then you'll get to see the ending cinematic and find out what happened to the various people and places you visited during the game.
