Next Installment of the Horus Heresy Teased?

In their latest update, Black Library has begun teasing a few images of a future book they are trying to hype. Initially unveiling it stage by stage, it's obvious that they were trying to garner as much attention as they could for what was to follow. What the final promo alludes to shows exactly why this might have been the case.

So yes, at long last we're actually getting a book where the Imperial Fists are a major faction. After all the long waits, short stories and events side-stepping their major conflicts, here we have definitive confirmation they're getting into a fight. Oh, and the Ultramarines are there as well.

From the cover and description, many believe that this will relate to the Imperium Secundus and likely connect with the recent events there in some way. Along with the Dark Angels and Blood Angels regrouping there, alongside the Imperial Fists major naval elements, Ultramar has become a bastion. Within the disrupting influences of the Warp, it's started to become an island of stability, holding together and gradually rebuilding, but reliant upon one location in particular for this: Sotha. Home to some unknown alien technologies, it has allowed the loyalists to penetrate the Warp within a set area, offering some links between their worlds.

While Unremembered Empire ended on a note of relative stability and consolidating their forces, the short stories have shown ill omens are afoot. In particular, the Night Lords legion has found their way to the world. Shattered and beaten as they are, they still remain a significant threat to the fledgling empire, especially if they were to drop their forces on a specific vulnerable point. Three guesses as to where that might be. Given the tagline and announcement that "Night falls across the Imperium" it's not hard to guess what this might be alluding to either.

Still, this is only a teaser but here's hoping we have great things to come in the near future.
