Darth Mortosis

Darth Mortosis was a Dark Lord of the Sith.

Biography
Darth Mortosis' life before becoming a Sith is unknown. The only thing that is known is that he suffered from an untreatable terminal illness for most of his life. For the entire time he was a Dark Lord, he searched for a cure for his illness. The only thing that interested him was finding a cure for his illness. Unfortunately, the most that could be done was give him life-preserving armor. Because there was no cure for his illness and because the armor was just barely keeping him alive, he decided that he would make it his goal to achieve immortality. He experimented with various types of Sith magic, but each attempt was a failure. Eventually, his illness got so severe that he could barely stand and relied on his subordinates to do everything for him, including continuing his research on immortality. Unfortunately, one of his subordinates grew tired of wasting his time trying to achieve an impossible goal and decided to kill him. To do this, he convinced his fellow subordinates that all Darth Mortosis was doing was prolonging his agony and the only thing they could do was put him out of his misery. That night, they broke into his labratory where he was doing more experiments. After a fierce battle, Darth Mortosis emerged victorious, until one ofhis subordinates destroyed the power source for his armor. With nothing to hold back the disease, he fell to the ground and died. What they didn't know was during the battle, a jar of parasitic worms that he was researching was broken, spilling the worms onto the floor. The worms then entered and reanimated his body. Fortunately, one of his experiments succeeded and his spirit was able to possess the worms, giving him total control of them. He also realized that drawing on the pain of death could enhance his skill with the force. He then caught and killed his subordinates as punishment for attacking him. After killling them, he used the parts from their lightsabers to build a new pair of lightsaber.

Powers and abilities
Darth Mortosis was highly skilled in using the force. Unfortunately, his disease had ravaged his body and limited his skill in combat. After being killed by his subordinates and reanimated by parasitic worms, his skills increased exponentially by drawing on the pain of death to fuel the dark side within him.

Lightsabers
Darth Mortosis wielded a pair of lightsabers. His lightsabers were a specialized pair of shoto that had a dual-phase function, allowing him to double the length of the blades at the push of a button. His lightsabers could also connect at the pommel to form a saberstaff. The blades of his lightsabers were crimson red on the outside and black at the core.
