Lantern of Antecedence

The Lantern of Antecedence is a finely built lantern made of sturdy green copper. Its globe features an intricately engraved image of a dwarf with its own lantern, darting after a shadowy figure. Both characters magically rotate around the diameter of the globe when lit. The lantern glows with a pinkish flame that shows events of an area up to one week prior to current time. It can only be used once per day, and the spell functions for up to one minute.
