Here are the last two maps that I drew for Fedor’s Pass as the party in the only campaign that interacted with it moved on to greener pastures after a single session there.
The first map is the top level of the Great Stair. The great stair was intended to be somewhere adventurers would find themselves using repeatedly to get so one the various levels of the dungeon. This level is just below the ruins on the plateau and doest connect to any other areas except via said stairs.
Finally we come to the palace level. This level is accessible from multiple locations, although not all of them have been mapped yet. For the level above the palace I ended up using the circle of doom map, but never got around to detailing the three levels below the palace.
