Editing Warhammer 40,000 7th edition (section)

===Chaos Space Marines===
* Lots of stuff on the Daemon Primarchs returning to aid Abaddon's Black Crusade.
* As mentioned above, Magnus the Red's attack on the Fenris system has brought the Planet of the Sorcerers into realspace, giving him the opportunity to launch direct attacks on Terra. 
* Fulgrim, Mortarion, and Magnus are able to sense the return of Guilliman and make their own plans to deal with their Loyalist brother.
* Abaddon nearly takes Cadia, but after a grievous wound from Saint Celestine and the Triumvirate overcharging the Cadian pylons he and his forces retreat. They manage to inflict major losses on the Imperials before being driven off- but not before Abaddon crashes his remaining Blackstone Fortress into the planet, destroying the Pylon system and causing Cadia to be consumed by the Eye of Terror.
