Kay is a GearHeart engineer, and devout partner of Alto. Both Kay and Alto grew up on a Syndicate planet. They both had very different lives. Kay was brought up in a wealthy househould, though he grew estranged from his parents over his lack of interest in the family business.
The estrangement grew even more at the introduction of an entrancing Helyk, Alto. Kay captured Alto's attention with his personality and aspirations, and Alto enthralled Kay with his artistic talent and amorosity.
Kay spent more and more time with his new romantic partner, mostly in Alto's tattoo parlor. He became a canvas for Alto, who covered him into emotion-driven luminescent tattoos. While Alto worked, Kay learned about the Apple of Hedonism. He saw into the different life that Alto lived. With Alto there was freedom, passion, adventures, and pleasures unknown. Kay wanted to be a part of Alto's life, as a way to abandon his own.
That desire would come true a year later, when Alto and Kay traded their old lives to start anew amongst the stars. Kay abandoned his home, his career, and his family to spend his life with the Helyk that had captured him.
