Phaser is the name given to all animals on the world. The legend is that long ago animals and people lived together. Wielders not only had the ability to bond with phasers but also wield the essence of their element to cast magic. During the Phase War, Wielders banded together to enslave the Immortal Elements. The water Wielders sided with the Immortal Elements and together they created the Mirror Realm. All the animals of the world were sent to the Mirror Realm where they would be safe. However, after the Phase War was long over many animals returned to the world to live and feed. When people tried to catch them they phased, or shimmered for a moment as they disappeared into the Mirror Realm. Thus, all creatures became known as phasers.
Today phasers are everywhere. Some live as pets, but most are wild. Wielders and their phasers wander the land honing their skill and earning league points in league battles.
A Wielder is someone who can bond with phasers. Wielders can only bond with one type of phaser. The basic types or elements are: Air, Earth, Fire, Light, Dark, Death and Life. Long ago, there were also Water wielders but the last of them were killed during the Phase War, five thousand years ago. Being a Death Wielder is illegal and needless to say there are very few of them.
Wielders often battle individually or on teams against each other. These league battles have become the biggest sport in the world.
