Ostia, the planet's only and largest landmass, is a land of both danger and opportunity. However, the once peaceful life was transformed by the appearance of monsters from the north. These monsters posed a grave threat to all races: humans, dwarves, and elves, all were slaughtered and abused by these monsters. They took great pleasure in abusing their flesh and plundering their property. Some monsters even considered other races food. Thus, war began. The human, dwarven, and elven kingdoms bordering the north signed a non-aggression pact, each building seven fortresses on the border to resist the monsters' invasion.
