"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.
This is a module file for the latest release. You need to change the extension to .team and put in in the modules folder of your ToME 1.0.5. Kudos to Darren Grey for reminding me to upload it here!
