What a module is
A module is a themed collection of real historical events — a period, a region, a subject — that you can play as its own endless run. Where region and era filter the whole library, a module is a hand-assembled set, so every round you get belongs to that theme.
How access works
Some modules are free for everyone. The rest are included with Terra Tempus Pro, which unlocks every module at once rather than selling them one at a time. The core game — the Daily Challenge, every region and era run, and Geo Drills — is free and stays free; a module is extra content, not a gate on the game.
Modules and your progress
Module runs count toward your era mastery and lifetime score exactly like a region or era run, and the events you master are added to your collection the same way. A module changes which events you see, not how scoring works.
