Tainted Grail Solo Play - Starter guide
What is Tainted Grail Solo Play?
Tainted Grail Solo Play, fully titled Journey in Avalon, is a standalone solo roleplaying game set in the dying world of Tainted Grail. No group, no game master, no corebook required: the book contains everything you need to wander the mists of Avalon on your own.
The setting is Arthurian myth turned merciless. Fleeing a plague called the Red Death, King Arthur led his people to the island of Avalon, only to find it anything but a haven. The Wyrdness, a primordial force that warps matter and mind, seeps through everything, and the colossal Foredwellers still walk the land. A century after the cataclysm known as the Fall of Avalon, what remains of humanity survives in scattered settlements. That is where your story begins.
The game is published by Studio Agate, the French studio behind Shadows of Esteren, and grew out of their Tainted Grail: Song of a Dying World roleplaying line, itself rooted in the world of the acclaimed Tainted Grail board game.
How does the system work?
Solo Play runs on a random-draw system: cards and tables act as your game master. You draw to discover where you are, what confronts you and how the world reacts, then decide what your character does. A streamlined version of Studio Agate's Story Arc system, the engine behind Shadows of Esteren, resolves the outcome, and your character grows between adventures.
Two things set it apart. First, the world remembers. Victories and defeats leave marks on Avalon, so your map slowly becomes a record of your own legend. Second, the book doubles as a toolkit for game masters of the multiplayer Tainted Grail RPG: the same tables that drive your solo sessions can generate adventure frames and side quests for a full table.
What do you need to start?
The Standard Edition is a compact A5 hardcover that contains the complete game. Add a pen and a notebook to track your journey, and you are ready.
The Deluxe Box is the collector's route: according to the publisher's campaign, it holds a limited hardcover with alternate cover art, a quest diary, the solo card deck, a map of Avalon, a battlemap, a pawns board and a sticker sheet. Nothing in it is required to play, but it turns your solo sessions into something you lay out on the table rather than just read.
Both editions are in English.
Who is this game for?
Play this if you want a full solo adventure rather than writing prompts: exploration, danger, progression and a world that pushes back. It is also a natural pick if you know Avalon from the board game or the video game and want to walk it at your own pace, and for game masters who want a tireless idea generator for their campaign.
Skip it if you are looking for a cosy or purely reflective solo experience. Avalon is grim, and the game leans into survival and loss. And if you only ever play with a group and have no interest in solo tools, the multiplayer line serves you better.
How does it compare to other systems?
Compared to Dungeons & Dragons 5e, the obvious difference is that nobody else needs to show up: no game master, no scheduling, no prep. The tone differs just as much, trading heroic fantasy for something closer to folk horror.
Compared to solo journaling games like The Librarian's Apprentice or Thousand Year Old Vampire, Solo Play sits at the other end of the solo spectrum. Journaling games hand you prompts and ask you to write; Solo Play hands you a living world and asks you to survive it, with rules, progression and consequences underneath. We traced that whole spectrum in our history chapter From full table to table for one.
Where do you start?
Start with the Standard Edition. Read the rules once, set up your first character, and let the first draws teach you the rhythm: draw, interpret, decide, resolve. Keep notes from session one; the game rewards continuity, and your record of choices becomes part of the fun. Expect your first character to suffer. In Avalon, that is working as intended.

The Standard Edition is the complete game and the right first purchase. The Deluxe Box is for players who know they will stay a while, or who simply want Avalon spread out across the table.
If solo play itself is what draws you, our Solo & Journaling collection gathers every game you can play alone, from The Librarian's Apprentice to Thousand Year Old Vampire. And if it is the dark fantasy that calls, the Fantasy collection is where Avalon's neighbours live.
