Biography
Sith prophecy ( before 137 ABY)

Thousands of years before his birth, the original sith believed that one day all the galaxy will be covered in darkness under the control of the darkside of the force for eternity under the rule of a sith ruler with divine power known as the dark one.

Many sith over thousands of years claimed to be the dark one but others dimiss the prophecy as a story, the sith emperor vitiate thought he was the one, after the great hyperspace war he took part in a ritual to grant immortality and lived for over a thousand years even though he was powerful he found a very rare holicron that contained immense knowledge and power of sith magic and realised through it that in order to have divine power you had to be the very living essence of the darkside so if he could succeed in the ritual he could take over the beings body and take that power for himself but he found that in order to succeed in the ritual he had to sacrifice his own life, unwilling to do this for he feared death above all else. Darth Sideous dismissed this claim as he saw himself the most powerful sith in the galaxy with no equal.

Creation (137 ABY)

Soon after his resurrection, the Sith lord Darth Krayt came across the ancient Sith world of Dromund Kaas. There he went to Kaas city and went in the citadel. There he felt the strong power of the dark side in the throne room and found a very well hidden secret room built behind the throne. In the room he found a holocron like no other he tried a to activate it but nothing, it took all his power to open it and was overwhelmed with a hologram of the ancient Sith lord Vitiate and taught him the most kind of powerful Sith magic even he had never heard of. Before his final death Krayt indeed attempted this ritual in the unknown regions, there he traveled to a unknown solar system full of life forms on different planets. The ancient Sith and even someone as powerful as Vitiate never attempted this ritual as it came with a price of their own life even though Vitiate was immortal but Darth Krayt knew he had an advantage, Krayt could resurrect himself and come back stronger than before. The ritual had consumed the entire solar system, trillions of lives and dozens of planets gone like the system never existed. The ritual took months to complete everything was comsumed by it lives, worlds, stars, suns even black holes and the Force itself nothing left but a child. Krayt was astounded with himself not only he did he survive the ritual he created the most powerful being in history, looking into childs pure black eyes made him tremble but saw limitess potential within the child, the living essence of the dark side in its purest form. Taken the boy back the known space and left him on Tatooine to wait for his return, not wanting anyone knowing of his existence. Darth Krayt never came back to claim for the boy for he returned to reclaim his throne but failed and was killed by Cade Skywalker leaving the child all alone on the dessert planet.
