Ahk'laht, a Noghri bodyguard of the male persuasion, was tasked with the protection of Leia Organa Solo while she carried out her responsibilities as an ambassador.
Ahk'laht grew concerned during talks between Leia and a Barabel ambassador concerning entry to the Alater-ka spaceport. He worried the Barabel might physically assault Lady Vader in an attempt to frighten her. As a result, he intervened and knocked the ambassador out.
This event, coupled with existing strain from Mon Mothma and other New Republic officials—including an Elomin representative who accused Leia of being a "slaver"—ultimately led Leia to decide to send the Noghri back to their home world. Leia then directed Ahk'laht to get in touch with the clan leaders on Honoghr and inform them that he, along with the other Noghri, were on their way back.
