There are four continents: the South, home of the Barren; the North, home of Prosperity; the East, home of Nature; and the West, home of the Cold. Each continent houses its own beasts, and aspiring tamers face their trials in order to bond with them.
Long ago, humans fought beasts known as spirits. One day, a human and a beast grew close, forming a bond that transcended the conflict. To solidify their connection, they performed a ritual, marking the human's hand and strengthening their bond. This human became known as the first tamer. Over time, the practice of taming grew in popularity, leading to the world of beasts and tamers we know today.
