A sunset spell is a spell meant to protect things of magic stolen from their rightful place. A sunset spell is activated either when the lid is removed by the one who took the things, or by the proper touch of a wizard, via his blood or saliva. The spell plays a small tune when activated and waits until the next sunset, when all of the stolen items are destroyed in a massive explosion. Zedd activated a sunset spell while he was held captive with Adie after being taken from the Wizard's Keep. He intended to destroy all the stolen items, as well as kill himself and Adie, saving them both from being tortured by Jagang.
