Lost Souls is a MUD, a free text-based multi-player online RPG (role-playing game). The theme of the setting is medieval fantasy, with elements drawn from a wide variety of sources alongside entirely original content. Your character in the game battles monsters, develops skills, advances in ability, pursues quests, and explores the wide, detailed world. Lost Souls was founded in 1990, and has been under continuous development for thirty-two years. While many MUDs regard themselves as essentially finished works, Lost Souls takes pride in always working to improve its technology and design, reinventing the game experience continually.
