Atonement of Harmony
The Kingdom of Castrona was a nation located on Isteroxe. Castrona was located in the region of Larusia. Though Castrona was a monarchy, the monarchical pieces of its government were mainly for ceremonial and traditional purposes, and the queen held little actual authority.
In 2097, Castrona became part of the Larusian Hegemony, thus forsaking its national sovereignty and causing the nation of Castrona to cease to exist.
