Editing Warhammer 40,000 8th edition (section)

=====[[Ultramarines]]=====
*The Ultramarines' 2nd Company is now led by Captain Acheran, as [[Cato Sicarius]] is now the head of Guilliman's Victrix Guard. Sicarius was lost in the [[Warp]] at the start of the Indomitus Crusade; while the Codex claims his fate is unknown, the Dark Imperium novel (which canonically takes place as the Crusade is ending) has since been proven that he is alive and well. All the other companies are still being led by the same Captains as before. Acheran is later slain during the War of Beasts, so it's likely Sicarius resumed his old position. 
*It is said that Cato Sicarius no longer seems to be as much of a glory hog as he once was. Many suspect that his time stuck in the Warp did much to teach him the difference between being a champion and a leader. 
*[[Varro Tigurius|Tigurius]] was nearly slain by the psychic backlash of the Great Rift's opening, but he was able to come out of his coma in time to rally the Ultramarines in the [[Plague Wars]]. He was also able to divine the location of the Hand of Darkness, and give this information to Eldrad (later leading to its recovery by Yvraine and the Ynnari).
*During the Plague Wars, [[Torias Telion|Telion]] ended up leading his entire Scout Company in defense of their training academy when it was attacked by the Death Guard. 
*Following the Plague Wars, Guilliman oversaw the rebuilding of Ultramar before being required to depart to other Imperial warzones. Afterwards, the Ultramarines are able to reclaim 3 of the 7 worlds occupied by the forces of Chaos in the vicinity of Ultramar, all while dealing with an Ork WAAAGH!
*Following intense debate about the implications of adding the Primaris to the Space Marine Chapters and discussions with Archmagos Cawl about the viability of converting existing Marines into Primaris Marines, [[Marneus Calgar]] volunteered to be the first to undrergo the "Rubicon Primaris" procedure. Despite dying briefly during the operation, he is successfully converted into a Primaris Space Marine. Varro Tigurus later undergoes the procedure.
*The [[Tyrannic War Veterans]] were officially given Guilliman's blessing in recognition for their show of adaptability in the face of a dangerous foe. Since then, many Ultramarines successors have created similar Tyranid hunter forces.
*Before being reunited with Guilliman, the XIII Legion had been known as the War Born, as the first members had been drawn from those regions in Terra that had been the last to submit to the Emperor in the Unification Wars.
*Calgar became seriously injured in [[War of Beasts]] and is recovering.
