"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.
It's taken me a few days, but I borrowed enough of ToME's code for death messages to work. You will now be told what killed you and the exact description will vary depending on damage type (e.g. physical, drowning, lava, fire).
