So It seems to me that every legion and primarch gets at least one book that focuses on it. Off of my head only Night Lords (who are featured in Unremembered Empire and Vulkan Lives), Imperial Fists (who will be showing up a ton when the siege comes around), and Iron Hands dont have books centered around them. Now by now we should all know what happens to the Iron Hands, so it seems obvious that Ferrus Manus won't play a part other then to haunt a certain character. But will his sons get a book, perhaps to reveal the turmoil in the legion after Istvaan? As an IH fan it seems a shame that they may not get a lot of air time as the series go on, and i may have to suffice with short stories and cameos in other works.
