Kurtulmakt (or whatever) doesn't give you exploration XP. I see it fine when all the places don't give XP but in this case it's a bit odd. In *spoiler* place, you have a way into couple other places too and they give you exploration XP and cost less to get there.

Another thing is that shady guy in lower who gives you keys randomly. There has at least been one key which you pay for (chosen temple key, I think) but disappears after a reset as it's a quest item.

Then, it seems that some of his keys don't work where they have fitted before. I don't know if this is intentional. Some DM who does things like this could perhaps PM me about the keys and I'll tell him more.
