How a round works
One round is one month
Give orders
Build, trade, raise troops and plan movements. Whatever affects only your own realm takes effect at once.
End your turn
Report ready. Until the settlement starts, you can take your turn back.
Settlement
The month is settled for all realms at once. Then the round report shows you what has become of your realm.
Every round has a fixed deadline. Until then you plan your turn whenever it suits you.

Play while the game grows
Ferrum et Fluctus is playable but not finished: rules, values and the interface can still change, and some things are still missing.
Your feedback helps decide what comes next.
