The skull symbolizes not only sacrifice but also the purity of humanity. The flesh of traitors, heretics, and xenos often deviates greatly from that of true humans, with one of the most distinct variations lying in their skulls.
It is for this reason that the skull serves as an emblem of human purity and the sacrifices made to defend it. Throughout the Imperium—from the Walls of Martyrs to skull insignias—it reminds all imperial citizens that "the blood of martyrs is the seed of the Empire."
Servo-Skulls are drone-like devices crafted from human craniums, typically taken from loyal servants of the Emperor such as low-ranking tech-priests or aides of the Administratum. A basic machine spirit is then installed, and peripheral systems along with anti-gravitic engines allow them to ascend from their mortal shells and hover through the skies.
Despite their vast numbers, being chosen for transformation into a servo-skull after death remains a great honor within the Imperium.
