The Legend of the Four Heroes

Arthur, the energetic lumberboy from the caelum forest in the east.
Trish, the dutiful paladin from the silver monastery in the white mountains.
Roy, the sly rogue from the salt coast at the eastern shore.
Miki, the mysterious mage from the Saladar forest at the Arlean lake.

Since neither could survive on their own, they decided to work together. As a group, they have been taking on many different contracts. Nowadays, they are known throughout the lands as the four heroes.
