Sleth is the big brother of Mori and Boyo, the children of Bram Cal, CEO of Cal United. His uncle Londy took him under his wing and taught Sleth almost everything he knew about the business the Cal's family is running for ages.

When he turned 16 he already knew everything about every rock, gas or ice in this universe.

Years later he went to the Science and Trade University, graduating Magna Cum Laude.

Today he runs under Londy's supervision Cal's United RCM Service Line (Resource Control and Manufacturing).

People love him because of his sharp mind for business and innovation.
Close ones say that he was maybe the only one that could get under Boyo's skin.
