The Blue Dragon by Salvador Mercer

A thousand years ago, on the world of Claire-Agon, a war raged between men and dragons.

After an expedition of elite warriors kills an ancient nemesis, Seth the Sword Slayer, one of Agon’s most feared assassins, finds himself in the middle of a mysterious string of killings targeting the members of his elite group.

As the Kesh wizards call a conclave of Agon’s most powerful realms to Balax, the capital of Balaria, Seth attempts to set a trap and kill the rouge assassin in his homeland with the help of the governor’s troops, the thieves’ guild and his own assassin’s order. Seth must not only save his city from a new threat of destruction, but also navigate the politically deadly waters of high intrigue from the gathered realms.

Seth soon discovers that, in the world of Claire-Agon, when dealing with a Blue Dragon, sometimes appearances can be deceiving.
