Kriek Savos

Kriek Savos was a male Human and former Jedi knight. Savos renounced The Galactic Republic and The Jedi Order and became a sith lord as part of The Brotherhood of Darkness.
Like many sith, Kriek Savos had a fascination with thwarting death. He spent much time experimenting with sith alchemy in an attempt to prolong his life. Savos died young at the Battle of Ruusan but before his death he managed to impart an avatar of himself into his battle mask. This avatar was not capable of manifesting physically but could interact with the minds of those who had worn the mask.
By the time of The Galactic Empire's reign, The mask of Kriek Savos was being displayed in Grakkus' safehouse until it was taken by The Crimson Storm.  

History

 

Early life & Jedi training

  Though Kriek Savos was born and raised on coruscant's lower levels, the Jedi order did not discover the young force-sensitive until his parents were killed by an armed man. Kriek was taken under the wing of Jedi Master Guido as his padawan learner. Master Guido was a green-skinned nautolan who was known to be composed and compassionate, Kriek grew to see him as a paternal figure after the loss of his father.
When Kriek was 11 years old, He participated in a jedi rite of passage known as the gathering. The purpose of this lesson was to teach younglings how to overcome their personal fears or failings. In doing so, they would find a kyber crystal attuned to their Force presence in the crystal caves of Ilum. Before entering deep into the Ilum caves, Master Guido told Kriek to follow his instincts and be mindful not to lose himself.
In the caves, Kriek was confronted with his kyber crystal on the other side of an impenetrable ice wall. When nothing seemed to make a crack in the wall, Savos lost his patience and began punching the wall in rage. The young boy bloodied his hand in the futile effort before slumping to the floor. After a brief reprieve, Savos reminded himself of the warning his master had given him. He focused and used shatterpoint to discover the weakest point of the wall. He impaled that exact spot and the wall crumbled, leaving him free to collect his crystal.
The Padawan returned to his master and showed off his crystal. Master guido was impressed but he reiterated to Kriek the importance of controlling his anger and not losing himself in the moment.  

Fall to the Dark Side & Death

  Like many Jedi who fell to the dark side, Kriek Savos was disillusioned from the jedi order because of their blind trust in the republic.
