Player’s Bases are scattered along the Continental and Archelelepo coastlines of groups of Sectors that make up the Zones within the game.  Each Base is in itself a Fjord system, a maze of channels and islands and as can be seen from the map below, there are only three entrances to the Base.  The numerous bottlenecks created by islands and peninsulas provide for the strategic placement of weapons and defense structures.  

Within this Base are numerous levelled sites, of various sizes, that allow the placement of Buildings, Walls and Weapons Towers

As players they reach higher levels new sites open up allowing them to build more structures and/or scatter their buildings over a larger area.
