Editing Warhammer 40,000 7th edition (section)

===Space Wolves===
*A few retcons about Leman Russ- some time after he was adopted by wolves, a hunting party stumbled across his cave and killed his wolf-mother. After killing twelve men in an attempt to protect his "brothers", the hunters realized Russ was special and convinced him to go with them to King Thengir. When the Emperor revealed himself, Leman Russ challenged him to a duel on the spot (no mention of any eating or drinking contests), which lasted for hours before the Emperor finally knocked him out. Apparently Emps KOing Russ in one punch wasn't flattering enough to justify being included.
*The long-lost 13th Great Company has reappeared in the Imperium. Unfortunately for the Space Wolves and everyone else, they've all turned into Wulfen and daemons seem to be following their every move. Needless to say, now that the Curse of the Wulfen is no longer the Space Wolves' little secret quite a few factions in the Imperium are convinced that the Wolves have some kind of Chaotic taint. And after being egged on by the Changeling, the Dark Angels have begun an all-out invasion of Fenris just as a massive Chaos attack is occurring.
**The situation goes from bad to horrible as the Thousand Sons invade Fenris yet again as a unified legion, with Magnus the Red himself leading their forces. By the end of the whole mess, one of the Wolves' planets is destroyed, the rest of them including Fenris are in shambles, Egil Iron-Wolf is dead, and the Planet of the Sorcerers emerges into the Materium over Prospero as the Thousand Sons begin their attacks on the Imperium in earnest. The remaining Space Wolves head off to the Cadian Gate to battle in the 13th Black Crusade.
