Mappa Mundi – An Exploration + Ecology RPG. A divided land looks to you to heal it from disaster. Explore the Wilds, encounter extraordinary Monsters, and write the chronicle that reconnects the world. Swear an oath to do no harm and illuminate a land shrouded by Fate.

Leave your sword at home. A sharp mind and a curious spirit are the only weapons you'll need, Chronicler!

Welcome, Chronicler.

Take a seat. Your first assignment has arrived. But before we send you out into the Wilds on your first mission, a reminder of why we do what we do. We are the Mappa Mundi Institute, and the people of Evasu look to us to make sense of their world after a hundred years of chaos. 

How do we do this, and what part is yours to play? With your training complete, the Wilds await. The old maps are useless, now. The old stories have been forgotten. Ours is a land that has lost its history. And your job? Your job is to write the new one.

But it is more than just people that await you beyond these walls.

Before the Flux came and cut us off from each other, this was a world teeming with life. Monsters, those majestic, enigmatic, fantastic conduits of Fate herself, roamed the Wilds, some giving blessings, others hunting; all living, all thriving. Go out into the world, Chronicler, and find them. Observe them. Document them. 

Protect them

You have sworn an oath to do no harm. These lands, and the people within them, are fragile. Your task is a dangerous one, no doubt, but to heal a place is to love it. This is your part to play.

Mappa Mundi Journey Deck Cards



  • Step out into the Wilds of a world that mirrors our own, beginning with the ten regions of Evasu, from Barbecia in the west to Zoumung in the east, The Kikal Rift in the north to Aishamet in the south.

  • Explore varied ecologies, and encounter monsters, creatures, and cultures divided by a century of ecological disaster. 
    Study monsters and creatures like a naturalist, not like a hunter. Uncover behaviours unique to each being using your skills, talents, and special interactions without doing harm.

  • Engage in emergent gameplay using the Journey Deck. Travels through the Wilds are shaped by player actions. Narrators build a fresh deck each and every chapter, reflecting the information and intelligence players have (or haven’t) uncovered.

  • Shape the world as you experience it through collaborative storytelling between Narrator and Chroniclers. 
    Write the story of this place, mapping the lands you pass through and telling the stories of people and monsters you meet along the way.

  • Experience a different kind of TTRPG gameplay: solve problems through Traversal, Exploration, Deduction, and Observation rather than through combat.

Mappa Mundi – An Exploration + Ecology RPG will include:


  • A 200+ page core rulebook, including 100+ pages of lore, regional descriptions, and story hooks.

  • 4 Character Licences and full skill paths: will you be an Archivist, a Diviner, a Fixer, or a Guardian? How will you Specialise? What multi-Licence Endorsement will you accept?

  • 30 fantastic Monsters and 50 Creatures to encounter and engage with, including full behaviour profiles for each entry in the bestiary.

  • A 72-card fully illustrated Journey Deck to structure and visualise your time in the Wilds, including 38 landscapes, 30 Monster cards, 2 Creature cards, and 2 Opportunity cards. 

  • A comprehensive Narrator’s Guide, filled with advice on how to run campaigns, sessions, and one-shots for Mappa Mundi and guidance on how to create your own Monsters and adventures.

  • PDF copies of all 10 regional maps, both blank and illustrated. Players can map their journey through Evasu, shaping the world to reflect their own experiences.

  • PDF Character and Chronicle sheets. Bring your Chronicler to life, record their experiences and development, and write your story as you experience it.

Crowdfunding backers will also receive a free PDF – Chronicles of the Wilds – that includes at least three prewritten Mappa Mundi adventures, excellent as a starting point for new Chroniclers and Narrators or for those looking to jump right into a new region.

Chroniclers begin their journey with a Starting Licence, making use of Skill Paths to learn new skills and move towards gaining Specialisations. Chroniclers may use the Skill Paths from any Licence, working towards becoming a multi-Licence expert and receiving an Endorsement in return.
