The pupal stage in the developmental cycle of a siren, the pit sylph often inhabits old wells and mine shafts. Luring victims with a highly adaptable range of pheromones, the Pit Sylph will pull people into a sudden, sheer fall down into the water table below, often completely pulverizing the bones of the victim. While the pit sylph will eat most of her catches, she is required by the Imperial Piscines to regularly pay a pole tax of seven live men and seven live women a cycle. While not officially allied with the Imperial Piscines, sirens often work closely with them for posterity’s sake despite their occasional forays of involvement with the Vodyanoi (from whom they’ve collectively acquired a taste for horse meat.)
