This is my interpretation of Level 18 from the module, Dungeon of the Mad Mage.
Vanrakdoom. The dark fate of Lord Vanrak Moonstar. A level controlled by servants of Shar and creatures of shadow.
This is the first release for Level 18 and includes Map A, B, and C, spanning the north and west section of the level - the areas that have not fallen into the Shadowfell.
Umbraxakar awaits!
