This third book has Tory and Maelgwyn, united in one soul-mind, moving into another plane of existence to become Masters of the Cosmic Logos.
Given charge of their home galaxy, the soul-mind that was Tory and Maelgwyn is responsible and answerable to all the affairs that unfold within that galaxy. Those of the "Chosen" who now rule their home planet of Kila are not so much admired by the other human breeds as were Tory and Maelgwyn, and the pact that they had in place threatens to be pulled asunder.
As Tory and Maelgwyn struggle to perfect their formless means of guidance, the four "changelings", two human two deva, prove to be their link back to the land of the living. But will the elders of the Nefilim and their "Chosen" listen to the counsel of the youngsters before intergalactic war brings their leaders into disrepute with the Cosmic Logos?
