As a symbol of their (perhaps begrudging) respect for the Inquisition and its power, the Daughters of Guilliman - and other Britannians - often wear the holy symbol of the Inquisition, and even perform any religious rites pertaining to the Inquisition that might be expected of them, but they do not serve it directly like most sisters of battle do. To the people of Britannia, the Inquisition has come to be seen as an uneasy ally, and one the people often disagree with at that, but nonetheless one they obey, given the Inquisition's authority and fearsome power. Together, these two groups form the modern Knights of Britannia, and even keep the original name when mentioned as a unified group, but, given the bureaucracy of convoluted structure of the Inquisition, they avoid having any official ties to the Ordo Hereticus, as the Knights of Britannia officially includes both male and female soldiers, and the order does not always adhere to modern Imperial doctrine. The local Astra Militarum were joined by a unique local order of power armored soldiers who seem to cross the role of elite warrior and law enforcer these "Knights of Britannia" eventually went on to become the Daughters of Guilliman and the associated Space Marines, the Sons of Britannia. When the dominion of Macragge was being restored, Britannia was found by a small fleet of Space Marine ships during a Chaos incursion the space marines and their ships were able to aid greatly in the defense of Britannia, but they were impressed by the tenacity and ingenuity of the world's planetary defense forces. Before the return of Roboute Guilliman, the people of Britannia were cut off from the rest of the Imperium, having lost the capacity for interstellar travel long ago, and having no substantial tech-priest presence in the system. The Daughters of Guilliman, while extremely loyal to the Lord-Commander of the Imperium nearly to the point of worship, are not well known among any but the nearest star systems. If they thought he weren't against the idea, they might worship Roboute Guilliman, as he is very much a 'savior' to them. Unconventionally, these Sisters do not serve the Inquisition, and they allow "battle brothers" among them, including but not limited to space marines. They hail from a little-known planet called Britannia (named after an ancient Terran empire by the scholars who colonized the planet long ago) at the edge of Ultramar. The Daughters of Guilliman are a fairly young Adepta Sororitas Order completely dedicated to the resurrected Ultramarines Primarch Roboute Guilliman, with loyalty to him taking priority over anything else.
