Who is Khabarakh clan Kihm'bar from Dark Force Rising and what is their importance?

Khabarakh clan Kihm'bar is a Noghri commando and the sole survivor of Team 22. Khabarakh agrees to rendezvous with Leia at Endor and then convey her to his planet. En route, he angers Chewbacca, who then attacks him. Khabarakh then tries to talk Chewie into his senses, only to stun him into unconsciousness. Later, Khabarakh teaches Chewie some of his lightning-quick attack moves. When the Grand Admiral Thrawn arrives at Honoghr, he suspects Khabarakh's story of survival and month's absence from duties, and orders him held for Imperial interrogation. The Noghri insist on following their own traditional methods, and Khabarakh is chained to a stake for days of public humiliation. Leia goes to rescue him, convinces the Noghri that the Empire has been cheating them, and Khabarakh declares he is honored to have suffered for the truth. He accompanies Leia on her return to Coruscant.
