Editing Warhammer 40,000 8th edition (section)

=====Other Codex Chapters=====
*The [[Blood Ravens]] get their own entry in the "Unknown Foundings" section of the Codex, coincidentally confirming that they've been "gifted" a handful of Primaris Marines. It is suggested that the [[Ordo Malleus]] may know who their Primogenitor chapter is, but the records that they have are sealed. Newer fluff confirms that the Custodes were able to traverse into the Dark Imperium and provide the Blood Ravens a portion of their geneseed tithes, along with staff and equipment to create Primaris Marines, with the missive to regroup and replenish their numbers as quickly as possible (good thing too, since Sub-sector Aurelia is now stuck in the Imperium Nihilus and there's no telling how long Ulkair's prison will hold him). 
**Examination of the newcomers' gene-seed provides the Blood Ravens' Apothecaries with startling revelations about the Chapter's origins, leading to the decision to ensure that nobody outside the highest ranking members of the Blood Ravens can learn of it. 
*At one point in the past, two Space Marine Chapters ended up being formed with identical names and heraldries (the Celestial Swords). In true [[Administratum]] fashion, the mistake wasn't discovered until both of the Chapters were wiped out by the 9th Black Crusade 200 years later.
*Though it is again noted that the Indomitus Crusade was unable to liberate or even reach many of the planets that had fallen in the Noctis Aeterna, the equally important point is made that it gave the Imperium as a whole hope that it could survive its darkest era since the Horus Heresy.
*The [[Black Consuls]], formerly presumed to be all but destroyed, have been rebuilt by an influx of Primaris Marines, as have the [[Scythes of the Emperor]].
*The [[Black Dragons]] were about to be investigated by the Inquisition again, but it was called off when the Great Rift formed.
*The [[Minotaurs]] are forced to make for Terra after a Death Guard attack ruins their gene-seed stocks.
*The Angels Revenant survived destruction at the hands of the Maynarkh Dynasty in Imperial Armour 12 after the Necrons cracked open their home planet and seemimgly drowned them in lava. When the Indomitus Crusade arrived, they were ready to declare them extinct until it was discovered that a few battle brothers survived to fight the Necrons under the planet's surface. The Angels Revenant have since been rebuilt with Primaris Marines.
