Concordia: Britannia / Germania

Each land colonist provides 1 movement step and each sea colonist provides 2, which you may distribute among your colonists. Sea colonists move only along rivers; multiple sea colonists may occupy the same river section (p. 2).

No. Each land route between cities and/or Roman castles can hold only 1 land colonist at a time (p. 2).

No—houses can never be built on Roman castles (p. 2).

No. You may remove exactly 1 connected bonus marker and take its good into your storehouse, and only if there is room there. If the good is food or iron, you may immediately use it to help pay for 1 new colonist (p. 2).

With the Colonist card, you may place them in your own cities, Basilia, or Colonia Agrippina. The Tribune also allows new land and sea colonists in either Basilia or Colonia Agrippina (p. 2).

On Britannia, each player starts with a land colonist in Londinium and a sea colonist in Portus Itius. On Germania, each starts with a land colonist in Basilia and a sea colonist in Colonia Agrippina (p. 2).
