The Adeptus Custodes are a glorious and much celebrated force. In the earliest days of the Imperium they marched to war alongside the Emperor himself, presenting a magnificent spectacle which echoed the majesty of the master of Mankind. Just as their weapons and armour have always been fashioned to reflect his martial glory, so too are the proud standards known as vexillas, which are borne to war by some of the most veteran Custodians. Few shield companies march to war without Vexillas rising above them.
