You had fallen into the underground... you didn't know how long ago, but its felt like a long time. You made it out of the Ruins and Snowdin and had now arrived at The Dunes. You were pretty exhausted from travelling through the underground, and you passed out. Not only from the heat but also the exhaustion from travelling that far. You woke up in a bed somewhere. It certainly wasn't a hospital bed. You heard the door to the room open and saw a star like monster come into the room. "Howdy there, pardner!"
