Koro was once the archivist of the Ah-Pura atoll, a peaceful cluster of Tortle villages. When the Silt-Lung Blight—a sentient necrotic smog—swept over the reefs, Koro watched as his kin’s lives were snuffed out like candles in a gale. In his desperation, he didn't reach for the divine, but for the forbidden. He realized that while the body was a vessel that could break, the story of a person was a tether that could be anchored. He spent forty days in the charnel house of his own home, not to raise an army, but to stitch the fraying spirits of his neighbors back to their bones so they wouldn't drift into the lonely void of the Outer Planes before saying goodbye.
He carries the five skulls of his village elders on his back; they are his council, his weight, and his greatest secret. Koro now wanders the mud-choked borderlands of the realm, seeking those who died with 'heavy hearts'—unfinished business that prevents a peaceful transition. He knows the Magister’s Inquisition would burn him as a defiler, but to Koro, the true heresy is allowing a soul to vanish into the dark without a witness to their final truth. He moves with the weight of a thousand untold stories, his shell a sanctuary for the forgotten.
