Togruta Sith apprentice [Mercy]

Hello, this is my first request so I do hope someone gets interested in it.

This is the character of my brother in law, in a Golden Age of the Sith campaing I am running. The setting is the Old (Old) Sith Empire from before the Great Hyperspace War.

The name is Derbel Reythan. He is the son of a not very important Sith Lord who rules a small moon on Sith Space. He has lived a pampered life (If you can call being the heir to a Sith dynasty "Pampered"), secluded on his family castle. During his adolcence he has developed a strong bond with the dark side of the Force and he is already able to perform several Force powers like Force Lighting and Force Grip, but since he is just a beginner his demostrations are not that powerful. On his 18th birthday, he got sent to a Sith Academy on Ziost to start his path to become a Sith Lord (This is where the campaing is taking place).

Phisical description: A young looking Togruta male. He has a vertical scar over his left eye (Which is still on working condition) that he recieved from an over-zelous Sith sword practice with his father.

Personality: He is a bit of a spoiled brat. Egotistical and short-sighted. He wants to gain power just to humiliate his rivals and opponents, rather than to do anything in particular with that power.

Clothing: He could be wearing two different types of garments. The first one would be the clothes he used the first time he left his "home". This would be somthing inspired by the comics of the "Tales of the Jedi" series like: "The Golden Age of the Sith" or "Dark Lords of the Sith". Kind of Egyptian, kind of Medieval. With a lot of gold and showing some skin as well. Nothing too extreme, mind you.
The second set of clothing could be something more "Classical". Black robes, capes, hoods and all that jazz. This is from the time that he became a student in the Academy and he bagan to shift from Spoiled prince to Dark Side practitioner.

Weapon: If the drawing has him wearing the first set of clothing, then he would be wielding a classical Sith Sword. Given to him by his father on his 11th birthday. He actually despises the weapon and longes for the day he can build a fabled Lightsaber. The weapon desing is up to the artist.
If the second set is chosen, then he would be wielding a normal lightsaber with an Ebony blade (Fancy word for black, huh?). Again the specific desing of the hilt is up to the artist, as long as the blade is black.
Also! If it suits the artist. You can add a "Sith lanvarok" on his left arm. But only if you think it will look good and it's not a hassle.

Background: Something shadowy and dark. Maybe some large halls with high ceilings and long rows of colums. Something that represents a Sith Academy. I don't think the background it's that important really, its up to the artist. The only thing I request on this one is that is dark.

Stance: As long as you can make his look badass, it's allright with me. You should also take into acount that he is a budding Dark Side practitioner and probably should be seeing diplaying some sort of dark energies or something of that nature. Also: an image of him on the middle of using the dark side power known as "Hatred" from WOTC Darkside Sourcebook would be really cool.

I might expand a bit his personality as the campaing progresses. Do let me know if there is anything that needs clarification or if you need some reference pictures.

Super thanks in advance.
