Zylenia was founded in 2017 (AN date pending) in the island of the same name and was incorporated to Gerenia as a dependency under direct control of the government. The island had a Governor appointed by the President. The Governor for the greater portion of the island's time under Gerenian rule was Diren Birnat.
After the collapse of Gerenia, the island was infested by Raskol cannibals until its liberation by a passing allied expeditionary force, one conducting a freedom of navigation exercise between Talenore and the Hoennese island of Niijima in the year 1671 AN. Afterwards a new colonial administration, this time Constancian in origin and allegiance, was established on the island - which was rechristened as Zylenisí.
