A workhorse not only of the toxic Martian skies, but of distant worlds at the forefront of the Tech-Priests' expansion for millennia, the Archaeopter is an agile fixed-wing aircraft. Piloted by a member of the Pteraxii caste, whose legs and scapuli superior are hardwired into its controls, the nano-carbon fibre-weave of the Archaeopter's wings is capable of morphing – a property it shares with the Pteraxii flight packs
One of many specialised castes of cyborg warriors available to the Adeptus Mechanicus, the Pteraxii are optimised for instinctive reaction and agility. Pteraxii’s reflexes are accentuated by paring back elements of cogitation that impede their primary function.
To be promoted from the Skitarii maniples to the Serberys corps is a great honour. They ride swift quadrupedal constructs whose razor-clawed limbs allow them to manoeuvre easily over the most shattered terrain, while their riders are mag-locked in gyro-stabilised positions.
