The game card is the entire game, about 13k characters: every scene and rule, and the answers the AI referees from. Paste it into an assistant that can't open links, without reading it first: it gives the game away. The Skill installs The Severed Spire into Claude on any plan: download it, then turn on code execution under Settings → Capabilities and add it at Customize → Skills → + → Upload a skill.
The Severed Spire is a free tabletop role-playing game you play inside ChatGPT, Claude, or Gemini. Chapter 1 of a solo or two-player RPG campaign in a mile-high tower that sinks an inch a day; your save carries into Chapter 2 when it is out. 1–2 players, 1.5–3 hours a run. No signup and nothing to install: open it in your assistant, paste the play prompt into another, or paste the whole card where links don't open.
How to start
- Open it in your AI. Tap Open in ChatGPT or Open in Claude, and press send, or paste the play prompt into any assistant that can open links. No paid plan required.
- The game loads. The AI loads Ironquill, our small rules system for AI-run role-playing, and sets your company at the tower's severed base.
- Climb the spire. Describe what your climber does. The AI narrates, rolls in the open (in code if your app can run it, otherwise off the printed dice tape), and voices the lift-crews, the Guild that controls the climb, and whatever circles in the cloud.
- Save when you stop. Ask for a save code at the end of any scene. To resume, open the game again in a new chat and paste the code once it loads, or use aigamecards.com/resume. The code from the end of Chapter 1 will also start Chapter 2 when it is released.
Questions
- How long is the campaign?
- Chapter 1 is available now and runs about 90 to 180 minutes. It is the first of a planned three-chapter campaign; Chapters 2 and 3 are not out yet. Each chapter is a self-contained climb through one tier of the tower, and a save code at the end of Chapter 1 will carry your company and their choices into the next chapter when it releases.
- Do I need to play The Toll at Blackbridge first?
- No. The Severed Spire stands alone and teaches what you need as you climb. Blackbridge is a shorter tutorial for the same Ironquill system, so it is a gentle warm-up, but it is not required.
- Can I play the whole thing solo?
- Yes. Built for one or two players, the campaign runs solo with the AI as game master handling every character but yours. With two players you share a company and split the tower's decisions between you.
- What carries between chapters?
- Your characters, their injuries, gear, and the choices you made. A save code at the end of each chapter encodes that state; paste it to begin the next chapter, in the same AI or a different one, with your history intact.
