Heir of the Broken Seal

A dark fantasy action-adventure thriller about Vaelith Nightbane, a ruthless, disciplined assassin and last descendant of the bloodline that created the Unseen Coil, and Patheicus Vane, a physically weak but indispensable scholar. When competing factions of the Coil turn against them, Vaelith must protect Patheicus for survival and professional necessity, while his astronomy, memory, forgotten languages, historical research, and ability to recognize forged contracts repeatedly keep them alive. The Coil's founders altered a prophecy and forged its succession history, using Vaelith's ancestors' true names in a magically binding agreement. The rewritten seal grants the organization authority to execute its founder's bloodline, while the original seal could prove Vaelith is the rightful owner of the Coil. Their journey moves through assassination attempts, mercenary ambushes, the Observatory of Ash, rival Coil factions, a city without names, stolen true names, the broken bloodline, and the original vault, leading to Vaelith's choice to destroy the Coil or take control of it. Vaelith wins physical confrontations at a cost, while Patheicus grows from frightened observer into the person who saves them politically and magically.
