Great to see someone picking up an area in doomed Groam. Congratulations on your 50 post status Feral. Approximate size is laregly up to you. The predominate ethnic grouping is human, but you can go wild with other groups too. The red labels were used to denote areas of Groam that have managed to resist by-and-large the effects of the plague. The yellow labels are areas that have been taken by the plague and contact has been lost with them.
Hope it helps.
