“They hired a Stray.” We’ve previously established the existence of the Thirteen, a group of Wizards who are powerful enough to have territories of their own, important because wizards cannot co-exist, and if they spent too long in in the same area, they will either kill each other or explode. The Thirteen take their boundaries very seriously, but they are not the only users of magic in the world. Lesser mages, wizards not powerful enough to take and hold a territory, are called Strays, bereft as they are of a home. Many Strays sell their talents, and they tend to be more available (and way cheaper) than and of the Thirteen. They also tend to be of dubious character.
