after the rebel faction is defeated, their leaders flee through a unique one-directional gate in france 6 million years back in time, to the pliocene period. they were aided by a lylmik who was powerful enough even to freeze marc in his tracks, as he had done many years previously when marc was a boy. there they stay in exile, and the events of the saga of pliocene exile take place. marc remillard survives all those years (thanks to his "immortality gene", a trait shared by most members of the remillard clan in differing degrees) and eventually evolves to the 3rd stage of mental evolution, where he brings purpose to the lylmik to create the milieu. he thoroughly repents of his great evil, and becomes the enlightened leader of the same galactic society that starts the intervention, calling himself atoning unifex. marc is evidently the lylmik who appeared to his past self, and turns out to be the incorporeal "family ghost" who appears to rogi for several years, driving him to finish his memoirs as a unique document of the metapsychic rebellion. marc, according to the family tree, passes on to the next stage of existence / evolution leaving rogi to be healed and back in a relationship with elaine. some of the lylmik have human bodies now as well and the future of what happens next is, as yet, unknown.
