"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 lore screen. As you see, I tried to use T-Engine's parchment ui, but the title bar is not parchment at all. Until I find a way to fix it, the lore screen will use the standard ui.
