One misty morning, you decide to go on a hike in a nearby forest. The trail you follow is clearly marked without a chance of getting lost. But then you hear strange, child-like laughter. Curious, you step off the trail to investigate. You follow the laughter, traveling deeper into the forest, until a thick fog suddenly descends all around you. You can't see the trail. You can't see the trees. You can barely see your own hand. But you know with certainty that you're not in the same forest anymore. And a voice tells you that you don't have much time to find your way back before it is too late.
