A Peacekeeper Retrieval Squad was a commando unit that performed covert work and recovery missions for the Peacekeeper High Command.
A squad was sent with express purpose to capture Talyn and his renegade Peacekeeper captain, Bialar Crais, it was led by Xhalax Sun. This was a deliberate choice by Command in an attempt to gain sway over Aeryn Sun and test Xhalax' loyalty. ("Thanks for Sharing")
