Moash was a nation-state on Trill.
During the planet's Information Age, Moash became engaged in a cold war with another nation, Vella, which included them backing opposite sides in a proxy war in the smaller nation of Dalaran.
In 2412 Tyria Sark gave Rear Admiral David Huntington a brief overview of the Dalaran conflict, comparing it to the current Moab Civil War and commenting that "It didn’t end well for anyone involved, the Dalarani least of all." (The War of the Masters: "The Silence Ends")
