Editing Warhammer 40,000 8th edition (section)

====[[Grey Knights]]====
*Some Chapters (most notably the [[Exorcists]] and [[Silver Skulls]]) have been known to notify the Grey Knights about potential candidates for recruitment within their own pools of Aspirants. The Grey Knights responsible for finding recruits are called the Gatherers, and they consist of Grey Knights who are too old or injured to take part in battle. Which makes no sense given current fluff states Astartes are functionally immortal and so aren't actually capable of being too old to fight. (There are exceptions such as the man Sigismund himself!) There would only be a few reasons for this, one is that this is proof that Space Marines are indeed affected by age (albeit slowly, so these Knights would have to be active since the Great Crusade) or while they are still powerful in their own right; the Gatherers' advanced age and/or crippling injuries have impacted their combat prowess to such a degree that they can no longer measure up to the Grey Knights' specifications but aren't maimed enough to justify being put into Dreadnoughts either. In either case, they're a lot like the Custodians' Eyes of the Emperor.
*With the Great Rift open and Daemons everywhere, the Grey Knights have their work cut out for them. They are especially active during the Plague Wars in Ultramar. 
*[[Kaldor Draigo]] notices that his appearances in realspace are occurring more frequently and lasting for longer periods of time; the Prognosticars believe that this may be a byproduct of the Great Rift weakening the veil between the Materium and the Warp, or perhaps it is a side-effect of Mortarion's return to the Materium. In either case, Draigo is prepared for a second round with the Daemon Primarch and we can only wonder what kind of new scar tattoo he's going to give Mortarion again.
*Due to the increasingly desperate state of the Imperium, Draigo has asked the other Grand Masters to consider executing the Terminus Decree (a.k.a. the thing in the Secret Box)- the first time this has ever happened.
*6000 years ago, the Grey Knights were successful in banishing Shalaxi Helbane, leading him to be thrown into Slaanesh's Palace of Punishments for his failure.
*Grey Knight Chaplains serve to ensure the purity of the Chapter, and are drawn from the very purest of the Paladins.
