Abandoned to die in the Labyrinth as a child, Savri was discovered by a man name Greck. Greck nurtured Savri back to health and adopted him. Greck led a settlement within the Labyrinth's interior called Daisycove. (the city surrounding the giant glowy sap daisy in the images)

Savri grew up in the company of the rough and tough people who made the Labyrinth their home, becoming a skilled warrior himself as he grew up. He often travels through the darkness to bring resources back to town. During one such venture, he meets Natalin, a star mage out of his element, and ends up saving Natalin from a monster.

From that point, the star mage stuck to Savri for protection.
