Spires: Stryx

The first models to 'fly' in the Conquest game. With bones lightened to the point where they can barely support the musculature that powers the powerful wings that carry them aloft, a Styrix of the Spires would be incapable of posing a significant threat on the battlefield were it not for their masters' cruel disregard for their lives... and the toxic, lethal load they carry in their bulging packs.
