Though the details of the incident that led the Spies to recruiting Rosales are classified, at least one eyewitness report suggests that, on the moment of the sword's activation, the blade began to glow with inscribed runes. These runes spelled Alexandria Rosales—the name they chose for themself—in a forgotten tongue. Despite the language being long dead, anyone who looks upon the runes knows for certain that they spell Rosales's chosen, true name, and that no other name will suit.
