Thick foliage surrounds a lone power pole in a forest clearing. Vines of ivy hug the pole tight from bottom to top. A dozen different lines stretch out in half a dozen directions — deep into the forest.

At a foot higher than an average head-height hangs a sign. It has no words, but instead a symbol. What exactly does the symbol depict? Is it a foot? A spaceship? A monster? A cat? Its meaning seems to shift depending on the angle from which it is viewed, and for that matter the mind that views it.

The sign has existed in this ancient forest for time immemorial, much longer than the wooden pole to which it is currently affixed. Many have journeyed here to decipher its true meaning — none have yet succeeded.
