Loban

Loban was a Sith who allied with his sister Alura to kill he former master Andreas. However his sister was unable to slay Andreas so he murdered Alura only to be killed himself when Andreas embraced the dark side.

Early Life
Loban had trained many years at the Sith Academy on Korriban with not only his masters but also other acolytes. When his sister, Alura came to him seeking change in the Jedi Order Loban saw an opportunity to kill Andreas.

Duel and Death
While Alura tried to sneak up on Andreas grabbing his attention Loban came as well. When Andreas tried to persuade his former apprentice to join the Jedi Order again he was enraged and revealed himself. He claimed that the Jedi Order's principles were misguided and false encouraging his sister more. After Andreas refused to aid them in their cause Loban resorted to killing him like he had before. The confrontation escalated into a lightsaber duel. Loban and his sister was able to keep up with Andreas' moves because she told him about the advantages and disadvantages. The two then relied on trying to double team him and outmaneuver him. As the fight went on with Alura being knocked out of the fight sooner than expected Loban engaged Andreas by himself. He defeated him by finding an opening and struck the end of his emitter. As Alura got back up from her unconsciousness, Loban commanded his sister to kill her master. She hesitated and finally settled with her decision not to kill him. Loban decided to take it upon himself but she defied her brother and Loban now having no use for her killed his sister. This sparked anger in Andreas who punched Loban and he retreated to get Alura's lightsaber. As the two reflected on the past and embraced each other, Loban decided to kill Andreas but he retaliated and with the dark side fueling him he used Juyo. Overpowering him and barely able to see any of his strikes and was cut across the abdomen then stabbed and died quickly.
