It was revealed to me as I searched the Internet for information on the HH Weekender as last year small amounts of information were released on the Run up to the event. I found the Schedule for the Weekender in the Black Library ticket section on their website. You can see an image of it below.
As you can see we will be learning all about it on Sunday at 10:00.
So Conquest. What would it be about? So who got Conquered and when? There was a lot of Conquering going on in the 500 Worlds and the Thramas Crusade. Could it be a book featuring the Ultramarines and Dark Angels? They did their share of Conquering in the Great Crusade. Maybe a revisit for the Night Lords and Word Bearers?
Looking less likely it will be Russ previewed at this Weekender now.
