Welcome to Ur-Dungeon. This is a collaborative world-building game that aims to do two things. First, it is intended to be an enjoyable experience in and of itself, designed for several players to collaboratively develop lore around an Ur-Dungeon. Second, it is intended to be a set-making and world-building piece for other kinds of role-playing games. This could be D&D, but just as easily any other TTRPG in which characters enter a specific place, interpret lore, uncover secrets, and engage in heroic action, or merely attempt to survive.
