This new dungeon is part of the Scorched Sky holiday. The zone-in is in Moors of Ykesha. It re-uses the same map from the Doomfire overland/dungeons back in Chaos Descending. Unfortunately, that map was built-in, so I had to make a copy. The file is named after the original overland. These settings are good for both the solo and heroic.
This new zone has a much higher "lava-level" than the original zone, leaving many areas inaccessible. Still, the original map is quite useful, and the process of "drowning" the map to make it more accurate to this holiday-only zone doesn't seem worth the effort.
