I love reading all the interesting takes on this portion of the game. about 3/4 of way thru ourselves we just finished the Tomb portion
(and I just finished writing it up
In our game, the animosity with Jarl is high right from the beginning, as they rescued Morgan Halverson and marched her back into the town after driving the hound off.
Reforming the next evening the Hound then slaughters a bunch of villagers and its all downhill from there.
By the time they get to tomb, its was no surprise the Jarl sent assassins to kill them. The PC's have succeed in usurping the Jarl's rule
at the end of the last session. The Jarl and his men haven't had their day in court yet however. play continues this weekend.
