The Inquisition: Legacy is a text-based fantasy role-playing game focused on immersive, player-driven storytelling. Launched in 1999, it is set in Urth, an alternate world where magic exists within a society shaped by fear, oppression, and the policing of moral and supernatural threats. Inquisitors monitor the population, while mages conceal themselves and wait for an opportunity to resist. The game explores the philosophical forces behind oppressive societies and gives players control over their characters and the outcomes of shared plots.

To support roleplay, the game provides tools that let players change room descriptions, use aliases, spread rumors, track in-character events, and create and sell objects. Experience earned through roleplay can be applied to improve other characters on an account, and players can use the “where” command to find active roleplay. The website also offers resources on the game’s cultures, characters, and guilds, alongside a wiki, forum, map, and guides. Players can connect through social media and find official merchandise through the website’s shop.
