Biography
Early life

Found as an orphan on Tatooine,Raymus was always bullied by "friends".His earliest memory was his "friends" hitting him.In the face of such adversity, the young Raymus was often forced to fend for himself and grew into a strong young man as he worked in the moisture farms.Even at this young age, he felt the calls of the Force and its dark side, and after one last and particularly brutal beating at the hands of his "friends", Raymus used its power to kill all of them, envisioning a giant wave of Force energy crushing all of his "friends"' internal organs.He would not understand his part in his "friends"' demise until many years later.

First steps in the Dark Side

After the death of his "friends",Raymus feared that he would be punished and left Tatooine on transit after stealing much of his adopted father's money.He was found by Darth Zannah on Nar Shadaa,who sensed the hatred mixed with fear inside him.She also discovered his raw talent in the Force and put him in line as a student in case her apprentice fails.Raymus was well-trained in lightsaber skills and the way of the force by Zannah.

Much to her surprise,however,Raymus was rallied by her apprentice to his cause and they both turned on Zannah.After an epic duel that lasted for hours,Zannah was struck down,with her apprentice declaring himself the new Dark Lord of the Sith,and Raymus as his apprentice,with a new name,Darth Cassus.

Treachery

After several years of training,Darth Cassus became more and more confident and eventually decided to turn on his Master.He and his new to-be apprentice,Stryfe,attacked Cassus' Master on his flagship,The Boma.Darth Cassus used an ancient Sith technique,The Spear of Midnight Black,to kill his Master.Darth Cassus became the new Dark Lord of the Sith and Stryfe was renamed as Darth Stryfe.

Downfall

Ten years later,he sensed that Stryfe was going to turn on him the same way he did his master.He decided that it would be difficult to find a new apprentice if he struck down Stryfe and the Order of the Sith Lords would be discontinued,so he took the initiative and crashed his shuttle into one of the asteroids in the Belgaroth Asteroid Belt.He was killed in the explosion,along with all 4 of his crewmembers.

Powers and abilities
Darth Cassus was a practitioner of Soresu.He was among the few Sith Lords who practice it,as other Sith Lords prefer the more aggresive styles.He also uses the Spear of Midnight Black,an ancient Sith technique that Kyle Katarn would eventually learn.He was also known to use Force Lightning to a certain extent.

Behind the Scenes
Like many other Sith Lords,the name "Cassus" does carry a second meaning(Casus is Latin for "death").He regards death as "simple as eating",and has massacred many.He disregards life,as many other Sith do.This notes that his name fits his personality quite well.
