Tonight tell us about something or someone mysterious.

A/N: My writing is rusty as hell. Not sure how well this qualifies for a character development community, so I'm just taking a shot in the dark to get started again.
Prompt: Mystery/Mysterious

Any object insulated in silk, in a warded box at the back of a dusty altar is an object to be respected. This is no exception, and the thief has come prepared. With a bit of charcoal, she sketches a rough sigil on the palm of her left hand, and a rougher one on the palm of the right. It's worth the risk. She knows it's worth the risk. Every broken promise, every warning ignored.  She half expects a shock like static when she lifts the dusty little box from its place on the shelf, but there is only the feel of rough, dry wood in her hands.  At last, it is in her hands.
