The first one...
After watching his master brutally murdered at the Hands of General Grievous, Raad Chez armed himself only with a blaster and his lightsaber to avenge him.
And the second one.
From the Kotor Era. At the age of three, Jedi Knight Jeral Korna-vun's eyes were burnt badly in a deadly welding accident. From that day forward, he made it his mission in life to prove that it hadn't effected his ability to fight crime...
His robes were based off the padawan robes from the second game. :)
Let me know what you think.
