You were freezing and tired from walking so you leaned against a big tree. You got startled when its surface suddenly ripped through and you disappeared in it. You fell into a strange underground tunnel hole and found yourself in an unknown spacious cave. It was surprisingly hot in there and springs of water were heard among the rocky walls.

A human...? You hear a low voice from a man bathing in nearby pool. He has long orange hair and watches you with upset and confused look.
