Raltharan
Raltharan was a Jedi Praxeum student on the moon of Yavin 4, studying under Jedi Master Luke Skywalker. In 14 ABY, Corran Horn chose Raltharan to be his apprentice, which occurred concurrently with Kyle Katarn taking on Jaden Korr and Rosh Penin as Jedi student apprentices. Raltharan eventually became a Jedi Knight due to Horn's instruction.
Behind the scenes
The video game Star Wars: Jedi Knight: Jedi Academy, created by Raven Software and launched on September 16, 2003, marked the initial, albeit brief, appearance of Raltharan. Within the game, the character's look is created randomly, and can be a male Human, Rodian, or Kel Dor, or a female Human, Twi'lek, or Zabrak. Raltharan received a mention later on in Troy Denning's book Dark Nest II: The Unseen Queen, which was released on September 27, 2005.
