Keepers of the Accord

The Keepers of the Accord are a Loyalist Chapter of the Adeptus Astartes shrouded in mystery and symbolism, thus worthy successors of the Dark Angels and Lion El'Jonson. Presumably -like their forebears and brother Chapters- the Keepers are part of the Unforgiven, the brotherhood of Chapters that hunt the Fallen Angels. However they are distant from their fellow Unforgiven, not because of a grudge or spite, but because of their creation. The Keepers of the Accord's exact Founding is unknown or forgotten, but they were founded on the order of the High Lords of Terra both as a political move and a strategic one. In return for the creation of the Keepers, the Dark Angels' behavior would be overlooked for a time.

The other side to the Chapter's birth is mired in classification and mystery. What is known is that the Keepers have always stood vigil over a wandering planetoid named "Thessalon" from a great space station acting as their Fortress Monastery of Caelestis Castellum. The Keepers of the Accord maintains a rather high number of Techmarines among their ranks, and thus have an impressive quantity of Land Raider patterns in their Armory.

Chapter History
The Keepers of the Accord are rarely seen by other Imperial forces with the Unforgiven Chapters seeing them the most frequently, but at their summits to hunt the Fallen, the Keepers only bring one or two companies of Battle-Brothers. Not that they have a distaste for others, indeed, those that have met a Keeper in person recall them being cordial and respectful but guarded with their words. Only, when other Imperial vessels approach their Fortress Monastery unbidden are given a single chance to withdraw before being fired upon. It would seem the only outsiders readily welcome are vessels of the Adeptus Mechanicus, whose occupants disappear into the depths of the planetoid the Caelestis Castellum follows.

While the Keepers focus on the defense of their Monastery and the strange Thessalon, they retain an ample service record of victories as any true Space Marine Chapter would, though few outsiders have heard of their accomplishments. Eldar pirates, Ork hordes, and Chaos fleets have been routed by the impressive firepower the Caelestis Castellum itself holds, not to mention the Keepers of the Accord's experience in void-borne combat.

Recently however, under the leadership of Grand Master Erathaol, the Keepers of the Accord have begun to reach out and provide relief and deliver the Emperor's wrath. And when companies leave the Chapter's fleet, it remains on high alert until they return. Currently the Chapter's fleet has tracked to the Ghoul Stars region of Segmentum Ultima, where they guard Thessalon amidst the numerous Dead Worlds of the region.

Chapter Culture
The Keepers of the Accord are monastic in nature, valuing wisdom and patience in tandem with martial prowess, much like their brother Chapter the Guardians of the Covenant. Battle-Brothers are very much encouraged to study the Chapter's extensive libraries on Imperial records detailing the Imperium's enemies, both alien and heretical. Despite the Keepers' high number of Techmarines and the seeming alliance they have with the Mechanicum, the Battle-Brothers do not give praise to the Omnissiah, but the Emperor and the Lion instead.

Chapter Combat Doctrine
Like all Dark Angel successor Chapters, the Keepers of the Accord are partially Codex Compliant with the 1st and 2nd Companies being elite formations named the Ironwing and Talonwing respectively. Due to the size of the Chapter's armory, the 1st Company has an envious number of Land Raiders and Dreadnoughts for the Terminators of the Ironwing to make use of to demolish an enemy.

Chapter Colors
The Keepers of the Accord's Power Armor is primarily sable black with dark green shoulder plates and helmets. The aquila or Imperialis on the chestplate and the shoulder trims are silver. The white squad specialty symbol is indicated on the right shoulder guard while Chapter heraldry is displayed on the left. Company heraldry is painted on the left kneepad.

Chapter Badge
The Keepers of the Accord's Chapter badge is a pair of white stylized double-edged swords running parallel, one pointing left and the other right centered on a field of dark green.
