donjon RPG Tools

donjon is the tab a game master opens when preparation meets an unexpected question. Its index leads to generators for names, weather, calendars, worlds, demographics, adventures, inns, towns, treasure and several kinds of dungeon. Separate groups support fantasy systems and editions, while general tools remain useful outside a particular ruleset. Most require no account and return an answer quickly, so they are well suited to live improvisation as well as supplying raw material before a session.

The collection has grown over many years and the experience is uneven. Some pages are polished interactive applications; others are compact legacy utilities with little explanation of sources or probability. A system label does not guarantee compatibility with the latest revision, and random output often needs editing to fit tone, balance and established lore. Accessibility guidance and change history are not prominent. donjon should be treated as a bag of creative dice rather than an authority: take the useful surprise, reject incoherent combinations, and verify any rule-sensitive numbers.
