A Guide to the Necromancer Bells

Seven bells are used by necromancers to summon and control the Dead. While most such bell-wielders will be Free Magic sorcerers, the most highly-accomplished wielders of the seven bells come from the Abhorsen family. They are always Charter Mages, and they use the bells to defeat the Dead and compel them to return into Death and pass beyond the Ninth Gate, from which there is no return.
