Having a really great time right now
Ah but we do know one important thing we did not know before, Borek of Karak Dum is an honorless traitor who abandoned those he was supposed to lead. Add the silent hold and 'they don't want or need help' is an entirely reasonable conclusion.
Would you have said the same if he'd gone Slayer upon reaching Karag Dum?It does not matter if he is sitting on a pile of corpses, he abandoned us without explanation after we swore to accompany him to hell. That is cause enough to deem him culpable all on its own.
Dwarves have so many issues they need an extra room of records and a dozen Longbeards wise in Grudgelore to help.
Maybe it's a party in there 24/7! Only one way to find out!To be fair the dwarves somehow did steal Moghur's powers and look what happen to them.
