1) Find out the houses of the nobles that Vrothlin supposedly killed. He will talk to Woland, get information from sources he has contacted, participate in a séance, whatever it takes.
2) Find any descendants of the nobles (above)
3) Start planning how to find out if any of 2 (above) are keeping the ghosts of Thorv's ancestors "captive"
4) Start planning how to free the ghosts found in 3 (above) including what rites would need to be performed if their souls are capured in blackened crystalized hearts
5) When doing 4 (above) find out where the entrance to Thorv's ancestral home is.
6) Get into 5 (above) and free Thorv's soul from his torment by performing rites found in 4 (above)
7) Rid 5 (above) of all invaders/monsters and establish a new Dwarf Kingdom.
8 ) Live happily ever after.
Okay, this may take more than one session or even a weekend
