Auric Aquilas (Imperial Fists)
The Auric Aquilas are shining, golden aquila icons, that are forged by the Imperial Fists Chapter and include shavings of metal taken from the Phalanx's armour plates. They thus benefit from a fragment of the mighty warship's fortitude and the protective aegis of its ancient machine spirits. This results in the Imperial Fists who wear the Auric Aquilas, to be shielded from hurts both physical and malefic.[1]
