ECOSEAS

ECOMsAD or the Economic Maintenence Division of South Avalonia (Vallisian: économique communauté maintien de Sud Avalonié division) is an economic, cultural and military union located in Southern Avalonia. It is mainly focused along the Paracas coast region, but membership is open to any nation in southern Avalonia.

It is primarily supported by military and financial personnel and resources from SiWallqanqa, the founding member, as most other member-states fall under SiWallqanqa's suzerainity.

The union was founded in 1968, and formalised in the Treaty of Tchetchuàn City, although the member-states had been in an informal alliance since the late 1920's.
