Your peaceful slumber in the forest is interrupted by a loud noise.
Ordinarily you, being the jaded and apathetic slug of a creature you are, would not pay this any attention.
However, this one is of particular importance to you for reasons that cannot be explained at the current time.
A quick observation of your surroundings shows two paths to take, the first being a massive stone door you only just noticed now, and the second being an opening in the forest directly towards the sound.
You are now faced with a choice, your favourite.
Follow the opening.
That door sounds cool, go to it!
I have a better idea.
