And you've already looked too long. Loner Cthulhu! is a minimalist solo tabletop RPG of cosmic horror set in the 1920s. You play a single investigator — scholar, journalist, occultist, or ordinary person dragged into extraordinary darkness — armed with a handful of dice and a story that builds itself. No game master. No predetermined path. Just an oracle, your questions, and the slow unraveling of your character's mind. Built on the Loner engine, it uses a tag-based system and a Sanity Track that doesn't just punish madness — it transforms you. The Unsettled see things the sane cannot. The Disturbed make leaps no rational mind could follow. The Broken speak truths no one understands. What's inside: A complete solo RPG playable with 4d6 and a pencil The Loner oracle with Advantage, Disadvantage, and the Twist Counter A Sanity and Corruption system where madness reshapes your investigation Lore on the full Mythos hierarchy and dozens of random tables to fuel every session The stars are almost right.
