I was figuring on setting it a bit before that.<br/><br/>Behemoth at Ultramar was 745.M41and the 13th Black Crusade was 995.M41<br/><br/>How does 845.M41 sound? I'm not set on any exact date beyond pre Black Crusade, so if anyone wants to incorporate a particular event into their background, we can see if we can find a date that suits.
