Dethaalis, the ancient of shadows and darkness has been gone from the world for thousands of years, leaving his descendants to carry on his name and tradition through their blades. Yui'loon was born to The Creeds of darkness, intertwined with a partner as if they were one being in two bodies. They know nothing but each other and the art of murder. Dark secrets are kept from them, hidden in the shadows of The Creeds. Their methods to keep the assassin's bloodline pure and to develop the deadliest of killers can break the fundamentals of basic morals. Everything goes awry when Yui'loon is forced to make an impossible decision, changing his life forever while throwing him into a new light. One which will challenge everything that he's ever known. Family... blood and death the price. Yui'loon will do anything to protect the ones he loves. This is The Chronicles of Darkness, The Tales of Old, By Dominik Sorensen. Only the first part, The Son of Darkness is on Royal Road, but you can read the rest with the full novel. It can be found on amazon or kindle (the link is within my linktree). It's only the first novel dedicated to a much larger series.
