- "What do you want?"
"I want what every loyal Terran wants. To serve and expand the Empire."
- — Stephen April and Crowley, in conversation.
Xander Crowley was the warden of the Imperial Union's Illiac penal colony in the mirror universe. A man with thick, sand-colored hair, perpetual stubble on his chin, and a greasy, ingratiating smile, he spoke with an accent which on Earth had belonged to Australians, but like other accents had survived decades of dislocation.
In 2385, following interception of a communiqué from Starfleet Headquarters aimed at Qo'nos regarding April, Crowley sent the information to April in exchange for records obtained by the ISS Arcadia, which contained designs for a neural neutralizer developed in the 23rd century by Simon Van Gelder.
