With the Emperor's Children restored to their former title, and the means to save them from the Flesh Curse assured, their Legion has a future once more.
Yet it is also a time of mourning, for Fulgrim was found only to perish. The cause of his death was, it seems, the very curse that had afflicted his Legion - he was a brilliant star, a beacon of light and power, but he burned too bright.
More proof, as if it were needed, that Primarchs are mortal after all.
Corax of the Raven Guard is on the mend. A few weeks of rest, a month or two at most, and his wounds will have healed completely. The Emperor's will is that Horus' crusade continue as it has, and he welcomes all Legions who wish to do so to join in Horus' mission.
It seems that the Emperor has found a suitable target, an end goal for the Crusade; a distant world, still out of reach but tantalisingly close - the Ork-held world of Ullinor.
With commanding the Legions from Terra becoming increasingly impractical, it seems inevitable that the Emperor will name his Warmaster once Ullinor is taken. These coming weeks and months will bring that world to within striking distance of Horus' Crusade. Now, more than ever, is the time for each Primarch to prove their worthiness to lead.
