Outlands

My home is my skeleton (AR1100)

   The first thing you will meet here is hostility in the form of grunks. They should not be to difficult to kill, the area is relatively small and the main thing of interest here is a big skeleton. The part you are interested in is the head. In the head is a stairway down, through which you can go to enter Fhjull's home (AR1101).

A good deed

   Talk to Fhjull and find out that he is not a big fan of Fall-from-Grace. Ask him about Trias to learn that he was tricked by him and is compelled to perform good deeds, which he hates. You can get several items from him (for free) and a place to rest. When asked about you mortality he will tell you that you need to go to the fortress of regrets. He does not know how to get there but he can tell you who does (350000XP). The answer can be derived from the Pillar of Skulls. He will then tell you that a portal exists to Baator located at the hand of the skeleton.
Now before you head to the portal do not forget to ask him how you can get back (100000XP). The way to return is to cut your tong with a piece of obsidian.
