Where Your Paths Crossed:

Location (N/A): Can't really fill this out as the options since it clashes with the KOTOR jumpchain starting location, and there isn't anything tomb or Korriban-related.

Something Caught His Eyes:

Drive (Despair): It seems like something inside you broke a long time ago. Hope. Joy. A particular event in your life, or the environment in which you lived, has plunged you into a bottomless pit of despair. As they say, fear leads to anger. Anger leads to hate, hate leads to suffering. And nothing in the world leads more quickly to the Dark Side of the Force than suffering. It only took a second for the man who found you to read all this in your eyes, and much more.

Relationship:

Tyrannical: Like many Sith apprentices, the relationship you had with your Master was based on fear. He took great care, from the very start of your training, to make it clear that he could kill you in the blink of an eye or inflict intense pain at will. He taught you to hate him, and this prepared you for your final test without you being aware of it yet.

Master's Philosophy:

The End Justifies: Your Master believed that a true Sith should go to any length to achieve their goal, no matter the moral implications of their actions, whether it is murdering colleagues or backstabbing a foe. He taught you countless dirty tricks to use in a fight.

Credo First: Your Master was a passionate adherent to the Credo of the Sith, believing that the current structure of the organization is the only one possible and that questioning the Sith Code is unacceptable. For him, any divergence was cause for execution.

Austerity: Comfort and daily pleasures were banished with your Master. During your training, he imposed a Spartan lifestyle and constant deprivation, strengthening your self-discipline, and tolerance of hunger, thirst and pain, and taught you many techniques for surviving in hostile territory.

Headquarters:

Old Temple: Your Master had chosen an ancient Sith temple as his base, forgotten by all, lost deep in the misty lands of a planet that has never been charted. Its location was untraceable. The place, majestic but sinister, was imbued with the Dark Side of the Force.

Training Focus:

Force Oriented: From the start of your training, your Master noticed that you had certain ease in manipulating the Force and understanding some particularly obscure concepts. As a result, he decided to train you to develop your Force powers rather than your lightsaber skills.

Gain 1 Style Point, 1 Blade Point, and 9 Force Points

Your Lightsaber:

Double Blade: Quite rare among the Jedi, more common among the Sith but still unusual, the double lightsaber is the most difficult weapon to handle and the most dangerous for its practitioner. However, experts in the art of fighting with this type of saber are incredibly more lethal than others and excel in aggressive and fast moves.

Fighting Style: 1 Style Point and 1 Blade Point in total

Furious Style [-1 Style Points]: This style is probably the one that best incarnates the Dark Side of the Force since it requires its practitioners to let themselves be completely submerged by violent emotions in combat, especially anger. It is the most vicious form of lightsaber combat, filled with both fury and malignant grace. The opponent is flooded with a barrage of chaotic and erratic blows, delivered with a combination of speed and bestial force, halfway between the heavy blows of the Strong Style and the fast aerial attacks of the Acrobatic Style. The challenge for a practitioner of this style is to maintain his lucidity despite the rage that grows as the fight goes on.

Cold Blood [-1 Blade Points]: In contrast to many practitioners of the Furious Style, you have committed yourself to full days of meditation during your training to strengthen your mind. This allows you to keep your lucidity in combat while optimally exploiting your anger. Your emotions do not control you, you control them, and your movements are closer to those of the Jedi Vaapad than the Sith Juyo.

Force Powers: 9 Points in total

Level 1 Abilities (Each costs 1 Force Point):

Force Lightning [-1 Force Points, 8]: Emblematic Sith Force ability, consisting in delivering powerful electrical discharges to a target through the user's fingers. The intensity varies according to many factors, such as the user's talent.

Force Barrier [-1 Force Point, 7]: Defensive technique composed of Force energy, used to block out any potentially deadly elements such as environmental hazards or any type of projectiles like blaster fires. Takes the form of a wall or a sphere.

Force Sense [-1 Force Points, 6]: Telepathic extension of the user's mind, allowing you to feel the living beings around you - even through the walls - or any movement in a certain radius. Also considerably heightens the five senses.

Battle Precognition [-1 Force Points, 5]: Allows one to sense and foretell the flows of the Force while engaged in battle. Used to predict an opponent's intentions or the trajectory of blaster shots before they are fired. It also amplifies reflexes.

Advanced Force Push [-1 Force Point, 4]: Force Push applied with sufficient intensity to lift several men off the ground and throw them over a distance of at least 10 meters, or break down a metal door whose reinforcement is not too strong.

Advanced Force Lightning [-1 Force Points, 3]: Powerful electric discharge branching out into dozens of smaller forks thus allowing the dark side Force-user to reach multiple targets simultaneously, without any loss of intensity.

Force Wave [-1 Force Points, 2]: Same as Advanced Force Push but applied as a multidirectional shock wave that violently impacts any object or person around the user in a radius of between 3 and 5 meters.

Level 2 Abilities (Each costs 2 Force Points):

Heavy Telekinesis [-2 Force Points, 0]: Ability to telekinetically lift, throw and manipulate massive objects such as large groups of persons, spaceships, large trees or heavy boulders.

Training Events:

Survival: You still remember that damn feral planet you spent months on. A treacherous jungle spreading as far as the eye can see, full of deadly danger. How did you end up there? Did your Master send you there on a mission, or did your ship just crash there by accident? There, you experienced something that changed you fundamentally.

Law of the Strongest: You managed to survive on your own in this hell, and when you managed to escape from it, you were much stronger, tougher and tenacious.

The Holocron: As a part of your training, your Master once handed you a strange, dusty, ominous-looking Holocron and locked you in a room with the device, with only instructions to discuss it with the being who lived in it. And that's what you did, anxious but curious. What kind of information was stored in that Holocron?

The Founder: It was the datacron of one of the earliest Sith Lords. The knowledge of the Force and the dark side he delivered to you is priceless.

The Ziggurat: How you discovered this temple would be an interesting story in itself. Were you on a mission for your Master? Were you lost on a planet that once belonged to the Sith in ancient and forgotten times? Or was this entire journey just a dream induced by the dark side of the Force? Either way, you found something very valuable in that place.

The Fountain: The water flowing in it was black as ink. You took a sip and it was enough to permeate your very soul. It was pure Force, in liquid form. An incredible power passed through your veins.
