Jon Snow, disillusioned with the cruelty of Catelyn Stark and his place in the Stark family, flees Winterfell at the age of 14. His escape leads him into the shadows, where he is found by the Faceless Assassins, a mysterious order skilled in death, deception, and mastery of poisons and potions. Under their tutelage, Jon is trained to become a deadly assassin, mastering skills of stealth, combat, and transformation.
In the hidden depths of the Faceless House, Jon uncovers secrets that change his life. He learns of his true parentage—he is not just a Stark bastard but Aegon Targaryen, the son of Rhaegar Targaryen and Lyanna Stark. With his newfound knowledge, Jon becomes determined to restore the Targaryen bloodline, claiming the Iron Throne that is rightfully his.
As he refines his skills, Jon creates a potion—the Witcher serum—a mixture of alchemy and magic, granting him enhanced abilities that make him more than human. The serum transforms him into something akin to the deadly witchers of legend, with enhanced senses, strength, and the ability to heal rapidly. His destiny becomes clear: to take what was stolen from him and the Targaryen family.
