Among other things it is able to effectively duplicate the effect of the astronomican. If it is still around, perhaps as an Ultramarine secret, then if & when the astronomican fails they could use it as a replacement and set McCragge as the capital of a new ultramar based empire. It is likely though that they would need an awakened & healed Guilliman to get it working or maybe even to find it. Haven't read Unremembered Empire yet but IIRC if what I've seen on this wiki is right, it was destroyed.

And TBH if there's gonna be a new Ultramar-based empire I'm not buying it unless Sicarius takes charge. It worked in Shape of the Nightmare for a while at least.
