There is a lot of information out there right now from the new Blood Angels Codex. While a lot of things are going to repeat, because there really is a lot of information already out, I am going to post up what was sent in, along with any links to more information that comes up. So check the latest Blood Angels information.
Please take all information as rumor until the book is released, and the book is in hand.
Here is a link to the latest from QnA sessions on the Blood Angels codex. Quite a bit of information in there.
