Pandora's Box

You find a strange box tucked away under the rug by the tree. Who put this here?

It has no tag, label, or even wrapping paper. Only some ominous runes etched into its metal sides.

It has a dark energy emanating from it.

Psst.

You shouldn't open it.

Psssssst. Hey, kid. It's me, Santa. Let me out.
