A winding hallway

Without any other choice in the matter, you begin making your way down the mysterious hallway. You try to pay attention to the walls and floor to look for anything that can be used as a landmark to prevent you from getting lost. Unfortunately for you, there doesn't seem to be anything on these smooth stone surfaces. The stones don't even have mortar between them. Instead they seem to have been perfectly chiseled to fit snugly next to each other. The hallway goes straight for a short distance, but soon turns 90 degrees to the left. Then soon again 90 degrees to the right. The corridor changes direction so many times that you quickly lose track of which direction you were facing when you started.

You had hoped that you could find something, anything that could signal a way out, but after several minutes walking down this hallway you've still found nothing. Every time you bump into the sides, the cold stone on your bare skin gives you goosebumps. The silence here is deafening, only the sound of your breath and your boots breaking it.

Eventually, you see a dim light ahead, around the next corner. The moment you see it you sprint ahead, excited that the monotony of this place has finally been broken. When you turn the corner, you are greeted with a bright light emanating from an elaborate magic circle on the floor. It is sitting in the middle of a split in the hallway you're going down. You can choose to go down the left, right, or keep going straight, though from here you can't see very far down any of the options to make an informed decision.
