Two of the Aurel people had gone under. They slept, blissfully unaware of the world around them. Above all of this, the Greyhound sped through the liminal spaces. He has eyes for this sort of thing you know? Quite a few of them, as it happens. He is fully awake and in his element.
The clouds and the dark and the distance were not a problem for him, it was in fact the whole point, to explore unchartered territory. He knew the others would wake up...eventually.
