Horizon

Horizon (ホライズン) is a city in the Central Continent where the story usually took place. It was once ruled by Edgar Fromware and his father until they were overthrown by Rein Shroud, his companions and the soon-to-be knight captain Stella Enplace.

After Edgar's defeat, the Hero's Party has been banished by Horizon's citizens (who refused to provide provisions) because the Party refused to help of defeating the demonic Edgar and deeming Arios and his teammates to be cowards. Horizon now idolized The Shrouds as their heroes and given Rein Shroud and his companions any source of provision they've wanted even for free.
