I'm getting a pretty anti-Blood Angels/their successors vibe here, so I did some digging, and I'm thinking Raptors. If you don't mind my asking, why the opposition to the first founding legions? They're the most well-developed, and arguably the most interesting of the astartes, minus the Ultramarines maybe. I know I don't speak for everyone, but most of my knowledge is of the founding legions, specifically the Blood Angels, just because I find them to be among the most fun. Are you perhaps trying to foster knowledge of the lesser-known chapters or something?
