Haunting of the White Sparrow

Five years ago, when the fevers swept through town, so did the rituals, so did the fear. The fevers were bad. It took most of the towns folk. The towns and villages were much bigger then. Those that survived have started a ritual to prove their bravery. They gather every year, the night before the harvest, offering blood and courage to satiate fear. A fear they call the White Sparrow.
