Captain Creysis commanded a scout squadron of Ebruchi warriors, a unit of scouts belonging to the Ebruchi pirate group. This group of scouts operated from a hidden moon base, which was situated close to the borders separating Wild Space from the Unknown Regions. The primary duty of the scout squadron was to patrol the star systems surrounding the main vessel of Creysis's clan. During the year 2 ABY, the forces of Creysis came across the Imperial Star Destroyer known as the Admonitor, which was being led by Admiral Thrawn. Ultimately, the scout squadron launched an assault on the Admonitor, but they were annihilated during the resulting conflict.
