King of Heroes could go neck and neck with some superior fiends and made great contributions to defending Oars against the powerful dragonborn, and later emerged as top defenders of Oars.
One day, however, citizens in Oars heard the sound of an enchantment breaking up from the sky! A crack appeared on the Dimension Fissure! The elders of Oars injected their power into the Woodsoul and slowly closed the Dimension Fissure.
Oars would organize an Adventurer Arena every year to select the strongest from every class tier and award them the title: King of Heroes.
To face the threat, brave adventurers in Oars the Sky Utopia established an Adventurer's Guild to defend their homeland.
But one superior fiend reeking of chaos got loose and started attacking the enchantment of the Yggdrasil, as if it knew that the power sealing the fissure would be undermined once the Yggdrasil is destroyed.
