Not even a single clue has be found to reveal the origins of Sla'arth, but it is sure that, along with his brother MickB KhraxSquare.png Khrax, they are one of the oldest beings on Runeterra. They both acquired the secrets to becoming the almightiest beings that ever stepped on the land; practice. Together, the brothers trained their strengths to every possible edge, perfecting their already almighty powers every day.

While Sla'arth's mind remained clean and stable, Khrax's filled with greed and thirst for power, and he left one day without his his brother's awareness. In only a few days, horror and disturbance soared the whole nation due to Khrax's powers, misused for destruction. After a long time seeking for his sibling, they finally clashed one long-waited day, where a battle that the Runeterra civillians pleaded for. Their hopes came true as Sla'arth emerged victorious from the battle. With one final MickB Sla'arth R.png spell, Sla'arth established the end over his brother's tyranny.

Peace was finally restored over Runeterra, and finally realizing the potential of his powers, Sla'arth became a vigilant, vowing his best to defend the land from upcoming major threats. However, there was one special place in Valoran that Sla'arth took a special affection to: Freljord. The frozen aura from that place drew his attention, and eventually, ice blended with his ancient magic, empowering Sla'arth's already mighty abilities. Also on Freljord, Sla'arth clashed with MickB DewSquare.png Dew, the leader of a tribe from Freljord. Recognized by his strength, Sla'arth was called onforth by Dew for assistance. Warned about Dew's tale of the other tribe's wars eventually ending up destroying Freljord, he joined the League to defend his favorite territory from Runeterra alongside Dew's tribe, the Ancients, from the Avarosa, Iceborn and Winter's Claw.

"Sla'arth is, perhaps, the most powerful being in the whole of Runeterra. No one should ever challenge his power outside of the League, or it is going to meet a terrible fate."
