You start with Erik the Red and Harald Hardraade on a small piece of Ice representing Greenland. The first Gaia camp you encounter has a Docks, 1 Barrack, Archery Range and Stable + one Trade Workshop and a Transport Ship. That single Camp is guarded by 2 Berserks and 2 Longboats (close to Shore so Harald can kill them with ease)
The first bigger Landmass is two Iceland each having two GAIA Camps having Berserkers and Arbalest Guarding, 1 Castle, a lot of 4 Keeps, 1 Stable, 1 Archery Range and a Barracks each 1 Trade Workshop.
Further away from the Castle and more to the middle of the Island there are 2 Gaia Camps on each side having 2 Docks + 2 Transport Ships, each guarded by 2 Keeps and a bunch of Champions. With the total of 2 Transport Ships + the one you can train you should then be able to land further to the middle.
Iceland could really be bigger if the map size allows it (Frankly Geographic wise I think a Giant map is needed, else it looks very clumped). Propably Ludakris is best to keep an somewhat decent Geographic Accuracy
In the middle, there is Great Brittian and maybe Ireland I don’t know, it will be misshapen badly and geographically unrecognizable if you want to make the map balance but … I don’t care. Upon Landing, there are 2 Trade Workshops guarded by 1 Castle, 2 Siege Workshops, A bunch of Onager, Woad Raiders (Or Longbowmen + Halbs, depending on what you want historically). Further Inwards you will yet again find 2 Gaia Bases with 1 of each 3 Military Building.
In the middle, there is a Castle with 2 Trade Workshops
If there is space there could be small tiny island with one Keep on them
Gameplay-wise all Island could be connected with Shallows
And Thats the an “layout” map of what I had in mind 11. Believe me I had a lot of fun drawing that xD
