In your dreams, you are frequently a great hero and heir to a powerful throne. You save princesses, defeat evil witches, drive out dragons, stop monsters, and generally be the hero you always wanted to be.
Then you wake up to your boring life and boring job.
That is until one day a man no taller than your coffee mug appears on your kitchen table. The tiny man begs you to come and save the kingdom of Andipardmin which is besieged by an army of massive dragons.
