Wings of Sand

The hitman knows as "Sandman" has made a life for himself through the ways of murder and torture. Growing up he never quite felt complete, like a piece was off hiding somewhere from him. With little to none knowledge of his past hounding him, he lives on normally till a masked woman approached him offering untold riches for the heads of several people. 'Just leave the bodies right where you kill them. That's all you need to do.' The request surely was suspicious but he was not the questioning type. That was until he met Firebell one of his targets and ...a fairy, no they were all fairys. Why do they want the fairy corpses? What made him pause before the kill? And why is the main antagonist the flowerpots?
