"A fantasy d20-themed dungeon crawler", to quote DarkGod's comment. Inspired by Incursion by Julian Mensch. Made available under Open Game License. This is a non-profit fan project. No money is made. There are currently only two people working on the mod. However, we have released several beta versions so far.
The worldmap stairs tile has been changed from the last concept. Also, all stairs found on the map are now working (no superfluous ones).
Time to add more dungeons, methinks!
