STORY STARTS HERE

After many hours of tossing and turning you decide to get up and wait until dawn. You noticed how Rebecca slept with her face right in your feet, making you smile. When you walked to the edge of the cliff you noticed exactly why you couldn't sleep - there was a campfire and a lot of noise and laughing coming across the lake! This angered you, making you consider going over there with Rebecca and teaching those inconsiderate bastards a lesson!

But maybe you should rather let them be, as they could be very powerful or severely outnumber you.
