Apparently the local goblins in Shadow Glen don't like me invaded there homeland and desecrating the tomb of their most revered ancestor. Odd, must be a goblin thing. So end up beating up a lot goblins to get to the hall of ruin. Then I get a new thing called a goblin blood scroll which will reveal its secrets when the blood of Irgolomok's blood is used on it. It take a few tries to do it of course, it is a replayable dungeon so replaying is to be expected.
