Void

The Void
The Void is an area that exists in no place and at no time. There is nothing inside this area and it is not confined by the laws of space-time. This is where the Old Gods come from and it is also where Blackriver gets his elemental power, bestowed upon him by the Old Gods themselves.

Void
"Void" refers to nothingness. The strongest Shadow magic, the ultimate destructive type of magic, is capable of completely disintegrating matter so that there is nothing left in that area; this causes everything around that area to come rushing in to fill the void. Because of this it is also sometimes called gravity magic.

The Rising Moon Clan reveres the Void as a fifth element and utilizes it for their stealth techniques. It is possible to maintain a thin layer of nothingness around one's body, therefore making the person impossible to see as it is if they exist within a different dimension. This is how the clan is able to become invisible.

Later on in the series Blackriver masters void magic and is able to use it for various effects; in one instance, he is disarmed and creates a space of nothingness between his hand and his dagger, forcing it to come rushing back to his hand.
