World on the edge of the void

Itaris is a world known for its gloomy history and bloody wars. And since ancient times, human souls have been traded here. How did it happen that the most valuable gift presented to people by the Creators became ordinary goods?
It all started with an absurd deal, so stupid and absurd that it could never have occurred to anyone that the consequences could be so terrible and destructive!
Arthur de Reardor in childhood lost his soul and is now forced by hook or by crook to look for the opportunity to break his terrible contract. Our hero will take a heavy full betrayal and testing, concluding with people and nonhumans not always honest and profitable transactions for them. DOLOD AND WITHOUT WAY TO THE COARY TOMENT in the world, frozen on the edge of the void
