Important Object

An Important Object is an object that is important for a story. It is often a plot device, and it is also often shiny.

An example of an important object are the Silmarils in JRR Tolkien's Silmarillion, which are obviously important objects, since the whole book is named after them.

Suethor's will often give their Mary Sue an important object, either obviously canonical or uncanonical. Either way, it is a Charge.

PPC Agents often keep uncanon important objects because of the sheer shininess, the Ring of Sairalindë being a good (or bad, depending on your viewpoint) example. These can have consequences, however, and may be a very bad idea.
