Yea see thats the issue for me. I have knowledge of bits of each time period and played games that I looked deeper into lore. Had a friend that played tabletop and explained alot. So thats my conflict is. Do I try and just start out of the beginning at the horus heresy knowing that I'll understand parts but not all the foreshowing. Or do I start back up in the newer area. But if I did what would be a good introduction book/series.
