As the title suggests I'm looking at running a campaign starting part way through The Great Crusade which will culminate obviously with The Horus Heresy, and perhaps slightly beyond that with the Traitors fleeing to The Eye of Terror.
Has anyone attempted such a thing? Otherwise open for any advice from anyone really. I'm not to worried about dates places and numbers, the flow of time in space and the fragmented records such as they are written by the winning side will take care of much of that. I intend to send them out with an Expedition Fleet to catch up to the Crusade, fortifying the conquered worlds with The Imperial Truth. In time I will steer them toward and away from certain conflicts or events as needed.
My player group will be 6 players, I will give them a choice of playing a character from any of the 18 Legions.
Thanks in advance.
