"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.
That's a drow hireling after you've hired him. It's friendly and it just helped my ranger kill an opponent or two (that's why there's piles of loot :P)
