Cyrus Vulpa is an agri-world within the Golgenna Reach. The capital city is Vaxport. A young Inquisitor Felroth Gelt in his pursuit of the heretic sorcerer Saul Charyn tracked him to a hab-block that adjoined a Schola Progenium. Within, they found that the sorcerer had made a mockery of the Schola, turning the nursery into a midden pit where foul Nurglings writhed and giggled in the dark.
A native flower, initially thought useless, was turned into the potent anti-interrogation drug Sandstone by the Pleasuremeisters of Quaddis.
