Raising the ‘Sky Island’ proved to be just the turning point Marius and Morgaine wanted; but not in the manner they might have expected.
Even after all they’ve been through — because of all they’ve been through — Marius was on the fence about using their newfound power to save the world. The cabal, the ship’s crew, all who have survived their travels with them, have seen humanity at its worst. Society crumbling, malice borne out of supernatural corruption and out of the strictly mundane, friends turning on them or being turned upon by what’s left of the species. Was it really worth saving?
This is what the Black Man and the Green Lady, apparently, were counting on with Marius. They had already taken Morgaine’s measure, and while she is compassionate to a fault, she wasn’t turning for them. Ever since she liberated him from Marauder madness, Marius’ weakness has been exposed, and exploited by enemies and sometime-friends.
The change to becoming Chosen has only exacerbated his sense of alienation, his gut instinct to fight fate. Through a choice act of possession, the Black Man reminded — or assured — Marius that, while they may have been empowered to enact some grand destiny, they could still choose. To save the world, or to put it out of its misery.
So, it was something simple enough to make him feel foolish for stalling so long — just the act of saving his ‘niece,’ Artemis, from the Nephandi — for Marius to snap out of it and genuinely choose a side. Not even Morgaine could convince him, but just a moment with the bitter, resentful daughter of the Carlisles did remind him of what matters. That something matters, at all.
Now, things are moving fast for the cabal. Morgaine and Marius have hatched a bold plan to finally put a stop to the Red Star itself, to defeat the Nephandi and cancel the apocalypse. It seems fitting that the two of them were chosen for this, for the battle — and for the ending. Far from fighting destiny, they have embraced it; they are its instruments, pitting the will to exist against the will to embrace oblivion.
