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.
