The vast region south of the Elbert Mountains and north of the Radiant Mountains is traditionally known as the "Agostino Region," the location of the ancient Kingdom of Agostino.
This land is fertile and rich with Magic Elements. Decades ago, Aragon the First led his invincible Divine Descendant Legion to annihilate the Agostino Kingdom, incorporating it into the domain of Holy Fadlan, and named it "Thrace."
At the pass of the Elbert Mountains stands a strategically critical military fortress—Esengard, meaning "The Indestructible Steel Fortress City."
Two crescent-shaped twin castles span the canyon, the Magic Barrier revealing golden light patterns at sunrise, and the three-mile-long Cast Iron Wall at the pass glimmers in the morning mist.
This city acts as a natural barrier, separating North Aisier from Thrace.
