Head towards the opening

It feels longer than it looked, and you can't imagine how long it might've taken to traverse the side of the cavern at this pace, but eventually the exit looms in front of you, a passageway several times your width and height, pitch black past the entrance. The floor is smooth, making passage much easier, and after what feels like a significantly shorter time, there's a light steadily growing at the end of the tunnel.

The hallway quickly opens up into another room, much brighter and smaller than the last one. The walls and floor are green, coated with ivy and grass alike, giving the room a sense of warmth. In the very center appears to be an old well, cracked and faded with time, the base ringed by vibrant flowers. There are a pair of ornate marble benches on opposite sides of the well, seemingly a good place to rest. The only other object of note in the room appears to be a small wooden bookshelf, with a trio of books on its top shelf. Besides the door you've entered from, there's another hallway of a similar size on the opposite side of the room.
