"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.
With the recent prices overhaul, I needed a way to display new prices in a clearer way than 2000000 (which was how high the underlying value could go).
