Seven Heroes of Ezkrea, consist of seven members from different species, joined force and vanquished him. Upon his death, they removed the powerful artifact and decided to destroy it. The stone refuses to be exiled from existance. The stone is virtualy indestrutible. So, the seven heroes broke the stone into seven pieces of crystals which are now known as the Seven Crystals. Each crystal has it own colour and strength.

The crystals have seven colours: red, orange, yellow, green, blue, violet and purple.

The weakest crystal but easiest to master is Red Crystal, whille the strongest but toughest to master is the Purple Crystal.
