Terra Mystica: Fan Factions is an expansion that introduces 20 fan-designed factions to the acclaimed board game. Each faction brings fresh mechanics and strategic variety, enriching the classic gameplay while remaining fully compatible with the base game and the official expansions Fire & Ice and Merchants of the Sea. Designed to feel like a natural extension of Terra Mystica, this expansion offers enthusiasts new challenges, creative strategies, and lasting replayability. Each new faction introduces a unique mechanic, from Architects building Bridges to Selkies expanding on rivers. Some, like the Firewalkers, add new tokens and power systems, while the Time Travelers score across past and future rounds. With options ranging from treasure-hunting Goblins to terrain-shaping Wisps, this fan-made expansion adds rich variety and significant replayability for Terra Mystica players.
