Jaina Halcyon was related to the Halcyon family, which consisted of both Nejaa Halcyon and Corran Horn, among other Jedi. Like those in her bloodline before her, Jaina was unable to normally use the Force to perform such feats as telekinesis, but was able to absorb mass amounts of energy to counter her weaknesses. Jaina was believed to be raised as a Jedi within the New Jedi Order, eventually reaching the rank of Jedi Knight. She had also lived her life as a bounty hunter, and had been a member of various factions throughout her life.
