About this game

Your AI Game Master is waiting. Step through the portal and play full 5th Edition adventures — solo with AI companions or with friends. The world adapts to every choice you make.

A LIVING FANTASY WORLD
• Form a party with AI heroes or invite friends — every NPC has a personality, motivations, and tactics
• Step into hand-crafted adventures with proper pacing, mystery, and stakes
• Your Game Master is always available — no scheduling, no half-built campaigns

PLAY IN CHARACTER
• Roleplay through chat — your character speaks, jokes, persuades, lies
• Talk to allies one-on-one, or address the whole party
• Every word is in-fiction; the GM responds in kind

FULL 5TH EDITION COMBAT
• Real ability scores, classes, spell slots, and conditions
• Attacks of opportunity, concentration saves, legendary actions — the works
• Tactical positioning, reactions, and ongoing effects all tracked

YOUR HERO PERSISTS
• Level up, prepare spells, equip loot — your character grows session to session
• A campaign journal captures every quest beat, every NPC met, every choice made

LAUNCH ADVENTURE: GOLDVALE'S LAST HOPE
A snowy mountain village under siege by white dragons. Form a party of four, brave the Stormfang Peaks, and decide the fate of a people. Hand-crafted, hours of play, multiple paths to victory.

WHY POLYMYTH
• No scheduling — your Game Master is always ready
• No rules memorization — the GM handles every roll, save, and resolution
• Full 5th Edition mechanics, not simplified — real ability scores, classes, spell slots
• Multi-character parties — your NPC allies fight, talk, plan, and grow with you
• Adventures are written, not generated — quality scenarios with proper pacing
