He had been born on Korriban, the ancient homeworld of the Sith. When a few Jedi were doing a mission and exploring the Outer Rim for a cleansing of the galaxy, they found Tyros Mortem on the steps of the ruins of the Korriban Academy, he was a Human Sith Lord like Malgus, their faces had resembled much. The Jedi found he had Force powers, and brought him immediately to the Jedi Temple on Tython. He had been one of those people who could use the Force like no other, such as Anakin Skywalker (Darth Vader) who had been known as the Chosen One in Jedi lore, Tyros Mortem had been thought of as a new Chosen One, so the Jedi taught him in the arts of the Jedi ways.
