Location
The Serican Demilitarized Zone lies between the countries of Arsytia and Fengjiang, intersecting but not following the XXth parallel north. The Zone is approximately XXX kilometers long and 32 kilometers wide, extending in width by 16 kilometers on each end of the official international border between the two countries. Despite being a demilitarized zone, the region remains the most fortified border on Tellurus, a frequent site of military conflict in spite of the formal armistice between the two countries as per the Treaty of Gamtoi.

As the armistice treaty between Arsytia and Fengjiang does not detail the of the DMZ across maritime territory, the territorial waters off the DMZ remains a regular matter of contention between the two countries. Aside from the  Armistice Island where bilateral negotiations occur, the various islands off the DMZ are disputed and highly militarized.
