Aevum Realm Architect
Rise from serf to sovereign in a deterministic low-fantasy kingdom-builder. Download the files, load them into your AI, and play.
Aevum Realm Architect is a deterministic, low-fantasy kingdom-builder LLM RPG that runs on ChatGPT, Claude, or Gemini. You begin as a serf — one copper piece, no status, and a brutal medieval world that enforces rank at every turn — and work your way up through trade, war, and political intrigue to the throne of a realm.
The engine is two downloadable files: a master prompt (the rules and GM brain) and a nearly 30,000-word Realm Atlas (the world). The Atlas is the single source of truth — geography, economics, law, factions — and the GM is forbidden from improvising around it. That constraint is what makes Aevum feel like a real game rather than a story that quietly forgets itself.
