NOTE: There is a known issue with the most recent entries having screwed-up information and links. Some databases are out of sync and we haven't been able to fix it yet.
This DM map is not what it appears. :) Just because you can see into the next room does not necessarily mean you can get there from here. The fire is the portal to where you want to be. And yes, you can get to all rooms. You just have to find the way.
