Syirlabradawk, also known as Syir, was a male Wookiee who practiced medicine on Talus during the Galactic Civil War era.
As a Wookiee medical professional, Syirlabradawk was affiliated with the Aggregate Civil Liberties Organization. This organization supported the Rebel cause during the Galactic Civil War, which pitted them against the Galactic Empire. In the period following the Battle of Yavin, Syirlabradawk operated an A.C.L.O. clinic.

Following the Battle of Yavin, tensions rose between the A.C.L.O. and the Nightstrike Soldier Hegemony, a mercenary group from Talus that sided with the Empire. In 1 ABY, N.S.H. forces forcibly closed Syirlabradawk's clinic, leading to the Wookiee's imprisonment. Subsequently, Captain Vayde Quellium of the Rebel Alliance and Trezya Nenei, representing the A.C.L.O., dispatched a spacer to infiltrate the N.S.H. base. Their mission was to recover a seized medical shipment and free Syirlabradawk before he could be transferred to an Imperial detention facility. The spacer successfully sliced into the N.S.H. mainframe located within the base, pinpointing the Wookiee's location. The spacer discovered numerous prisoners held and tortured within the underground holding cells, one of whom was Syirlabradawk. However, the Wookiee declined to leave, unwilling to abandon the other captives. Consequently, the spacer agreed to assist the Wookiee in retrieving his medical supplies from the base, enabling him to provide care to the injured prisoners before their departure. Syirlabradawk managed to stabilize the prisoners and remained with them until an A.C.L.O. transport arrived to evacuate everyone.
Syirlabradawk appeared as a non-player character in Star Wars Galaxies: An Empire Divided, the 2003 video game that was a massively multiplayer online roleplaying game. It was developed by Sony Online Entertainment and published by LucasArts before its servers were shut down on December 15, 2011. Syirlabradawk was incorporated into the game as part of the "Crisis of Allegiance" storyline, specifically with the release of "Chapter 2: The Talus Incident," on August 1, 2006.
