1347: THE PESTILENCE IS NOT A DISEASE. IT IS A CURSE.
A Dark Fantasy Text TRPG Powered by Unforgiving D100 Rules & an Unfiltered AI Storyteller.
THE ENGINE OF DREAD
Why traditional AI chatbots fail at tabletop RPGs—and how code restores real stakes.
- AI hallucinates health points, combat outcomes, and hit chances arbitrarily.
- Zero tactical depth—combat feels like talking to a passive text model.
- Costly monthly subscriptions with strict token caps and aggressive throttling.
- Unconstrained, floaty narrative where actions carry no mechanical consequences.
- Code Decides Fate: Hard-coded WFRP-inspired D100/SL mechanics rule life & death. Zero AI stats hallucinations.
- Real Tactical Survival: 2:1 enemy turn ratios, tactical executions, and infection mechanics.
- Raw Compute at Cost: Bring Your Own API Key (BYOK). Pennies per session with 100% client-side privacy.
- Unforgiving Permanence: True permadeath. Dead characters turn into global mutated world BOSSes.
SURVIVAL MECHANICS
Six core pillars forged to deliver pure, unadulterated medieval gothic horror.
Pure D100 Rules Engine
The AI writes the narrative, but pure JavaScript code dictates probability. Every roll triggers hard-coded WFRP 4e Success Level (SL) math, dodge/parry checks, and lethal HP calculations.
Infection & Eldritch Vision
The Black Death festers in your blood. At 21–80% infection, unlock mutated visions and hidden eldritch clues. At 81–99%, gain high-risk physical advantage checks—if you dare push your sanity.
Scene-Reaction Executions
No tedious grid gridlock. Exploit claustrophobic corridors and environmental traps to counter 2:1 zombie turn pressure. Trigger high-SL critical strikes for visceral tactical decapitations.
Conceptual Companions
Companions aren't brainless stat blocks. They absorb horde pressure and hold strategic timers. When enemy numbers overwhelm their control threshold, face visceral, high-stakes loyalty choices.
Permadeath & World Bosses
Death is absolute. Upon hitting 100% infection, your character isn't just deleted—they mutate into a persistent Nightmare BOSS on the global world map for other players to hunt.
Airwall-Free Sandbox Director
No invisible walls. The AI Director silently restructures dynamic 10-node campaign outlines on the fly. Unscripted player choices dynamically reshape subsequent story arcs in real-time.
THE SHADOW OVER EUROPE (1347)
"In the year of our Lord 1347, the pestilence arrived not by rat or air, but through broken papal seals deep beneath Caffa. The Black Death sweeping across ruined Europe is no mere disease—it is a flesh-warping curse. Flagellants scour the mud-drenched roads, fanatical inquisitors burn whole villages to cleanse the corruption, and abyssal horrors stalks the shadowed cathedrals. Grab your lantern, check your blade, and pray your blood stays pure..."
YOUR KEYS. YOUR POWER. ZERO MARKUP.
