The Wygmy Siltstone Jet Vein

On an unencumbered hill that juts up like an incisor is a seam of black jet struck through with pyrite inclusions thick as a human head.
Deeper: Yes, it has been found and even has been claimed, though Lord Wygmy’s range of enforcing power is limited to routine surveyors and “mineralists” who continue to sap his money redrawing plans of attack for freeing the enormous wealth of gemstone without bringing the entire hill down in their efforts.
These efforts remain as crude scaffolding of imported timber [mud-caked].
Within the seam whose jet runs into the hill nearly 2/10ths of a mile, a family of aquatic perpasi paddles about in a series of freshwater pools and falls whose dark hollows are lit by the energetic sprig fae ever tapping the jet for light and warmth.
