In this world, you're either an Adept or you're not. An Adept has mystical powers, and it depends on what type.

You could be a Fire Adept, able to wield fire and combust material.
You could be an Earth Adept, able to manipulate stone and metal. Some aren't able to do that, instead being able to command plant life.
You could be an Air Adept, able to conjure lightning and/or enchant wind.
You could be a Water Adept, able to shape water and form ice.

Of course, there are two types of Adepts who share a symbiotic relationship: The Light and the Dark Adepts.

Although both possess telekinetic abilities, Light Adepts can turn invisible under light and are able to form light flashes and barriers, and the source of their powers come from the heart. Dark Adepts, on the other hand, can warp in and out of shadows and form dark energy for a multitude of uses, and the source of their powers come from the mind.

Seven girls find themselves on a journey that brings them together. Some of them knew each other before, but not to the degree that they eventually learn. Indeed, there's one underlying reason why they wound up in the same spot at the same time. One reason that is the genesis of an unbreakable bond.
