Sirra completed her rite of passage (which she was hesitant to do because of the supposed death of her friend Raaba while doing hers) during a fight with a Nightsister in the lower levels of Kashyyyk. Both Sirra and the Nightsister were swallowed by a syren plant, but Sirra escaped and grabbed a handful of fibers on her way out.
Later, after Raaba turned up alive, well, and promoting the Diversity Alliance on Kashyyyk, Sirra and Lowbacca accompanied her to Ryloth, where the pair were held against their will until they escaped. Sirra later accompanied a New Republic Senate team sent to investigate claims about the Diversity Alliance, and in frustration, smashed open a crate marked "medical supplies", exposing the weapons inside. She was employed as an emergency pilot for the New Republic.
Sirrakuk was first mentioned in the 1995 novel Young Jedi Knights: The Lost Ones by Kevin J. Anderson and Rebecca Moesta as the unidentified sister of Lowbacca. She first appeared in the 1996 Young Jedi Knights novel Young Jedi Knights: Darkest Knight by Anderson and Moesta, where her name was revealed as Sirrakuk.
