===Mustering Forces to Himself===
What Guilliman found on Sotha was a pre-Imperial device that acted similarly to the [[Astronomican]]. This device was known as the [[Pharos]]. Instead of a psychic lighthouse like the Astronomican, the Pharos shone like a lantern and illuminated targeted worlds in the Warp, allowing safe passage to them even through thick warp storms. As it would happen, it later transpired that the Pharos was of [[Necron]] design (originally it was made as part of a FTL communication network) and was powered by an imprisoned shard of a C'tan called Zarhulash the Potentate, which explains both why it's capable of piercing through the malaise of the warp's ill effects so completely, as well as why daemons seem to so revile the thing. Guilliman ordered that the Pharos be shone on Macragge so that lost loyalists' fleets could find their way to him though the Ruinstorm.

This had the intended effect as beaten stragglers from the broken legions of the [[Iron Hands]], [[Salamanders]] and [[Raven Guard]] found their way to Macragge. It also brought in those ships from the [[Imperial Fists]] Retribution Fleet that managed to retreat from Phall and some [[White Scars]] who were not at Chondax for some reason. Badly beaten, and with their own primarchs [[Ferrus Manus|dead]] or [[Vulkan|assumed dead]], they swore allegiance to Guilliman until such time as the Emperor could be aided.

Some [[Space Wolves]] and a fleet of [[Dark Angels]] led by the Lion also showed up, but Macragge had always been their destination, since they had business in Ultramar.

AND if that's not enough the '''entire''' [[Blood Angels]] Legion ''(except for about eleven men left on [[Baal]], the "Lost Sons")'' from the Battle of [[Signus]] turned up on Guilliman's doorstep too.

Now this is where it gets ugly: both the Blood Angels and Imperial Fists [[RAGE|were actually looking for Terra]], so it could definitely be said that all these arrivals starved Terra of valuable resources and actually hindered the war effort. In fact this was ''explicitly'' stated to [[Lorgar]] by [[Kairos Fateweaver]] prior to the battle at [[Calth]] (the only time both of the damn bird's heads were compelled to speak the truth at the same time): they warned him that if Guilliman died, then Horus would have no chance at the Siege of Terra.

However, it is also known the Pharos was simply one part of a larger galactic network. It may be that Guilliman was incapable of redirecting its energies onto Terra, implying he was simply making the most practical use of the tools available. Not only that, but the Pharos was described as an "empathic" device which responded to the desires of its user, but had mostly unknown capabilities. By shining it at Macragge, one could take from that that it responded to Macragge's (and by extension Guilliman's) desire to regroup and fortify. Which, given the Ultramarines just got [[Shadow Crusade|savagely attacked and mauled]] by [[Lorgar]] and [[Angron]], made sense even if it had poor consequences for the Imperium at large.
