Black Hole, White Fountain. The Ferryman Pentalogy, #4

The hologram faded away and a silence fell over the glade as Dravidian reseated himself upon the rock. Sthulhu remained respectfully silent. In his mind's eye Dravidian saw Pepperlung on the deck of their great dragger, The Vorpal Gladio, saw him glance over his shoulder at the prefect as his tone became grave: "Beware, Dravidian. The bride is just sightseeing but Asmodeus is here for you. You are the only ferryman up for elevation this year.
Watch yourself. There will be a test, surely."The ground trembled suddenly and the remnants of the cage rattled as a minor Ursaquake shook the glade, and the sun orb went from gold to orange. A horse whinnied in the distance and Dravidian looked out across Parvus' homestead to see a great steed leap up in its corral. The slightest push against the dilapidated boards would have freed it-but the creature either did not know or did not care.
The horse, however mighty, knew its place. It knew in its primitive yet tamed wiring what Dravidian, in his advanced and now liberated own, did not: that nothing lay beyond its cage that did not already exist in abundance within.
