Story: The Cornerstone[]

Though their bodies have the capacity to deflect the brunt of most weapon strikes, the vast majority of Akumites are pacifists. Their people are easy-going, placing the values of life and wisdom above all else. Koom belongs to a specific sect of the Akumites knowns as Guardians--the only of their race capable of combat. On the rare occasion that they view conflict as a necessity, Akumites call upon their Guardians to protect them.

In recent years, Akum found itself growing dangerously low on SOL (which Akumites feed upon to survive). The Amaari reached out to them, advising that Earth had an abundance of this precious resource. As a Guardian, Koom was sent to investigate. He now serves as a Master on the Dredgion to aid the Earthlings in reclaiming their home and establish a line of SOL for Akum.
