What Play Feels Like
What Do You Do in Mar de Oro?
Join a crew, expedition, household, regiment, investigation, or political cause. Cross contested seas and early air routes. Investigate failures, conspiracies, old systems, and impossible events. Decide what you owe to crown, crew, faith, community, and conscience.
The world will shape who you are. What you do within it is yours to decide.
Cross a Contested World
Travel between colonial ports, old roads, frontier settlements, dangerous interiors, and the first air routes.
Investigate the Impossible
Encounter Fortera phenomena, Moon-Affected people, strange creatures, lost structures, political conspiracies, and failures of Éterlumin technology.
Choose Where You Stand
Institutions have interests, limits, and internal divisions. Characters are defined by the loyalties they preserve, revise, or betray.

Create a character
Place. Formation. Calling. Bond. Burden. Purpose. Where they come from, what shaped them (culture, faith, class, institutions), the work the world knows them by, who or what they are tied to, the obligation, wound, debt or trouble that follows them, and what they want now. The Character Builder turns those answers into a shareable dossier. No account is required.
