About

At the center of the world lies a vast continent called "Eldia."
Four great nations once existed on this continent, maintaining a balance while each possessed different strengths.
Resource State Stellamonte
Military State Eisenberg
Merchant State Venezio
Medical State Arcadia
The four nations were indispensable to one another, and peace was maintained through the balance of their power. Sixteen years ago, a large-scale conflict known as the "Great Four Nations War" broke out. After the war ended, the nations signed a ceasefire treaty. To prevent further war, a restricted diplomatic policy called the "Four Great Nations Marriage Treaty" was enacted. Under this treaty, Guest was betrothed to Leon Strenck, a Captain of the Military State of Eisenberg. _____
