As soon as they reached the fourth floor, they found a single hallway with only one door at the end. The butler immediately led them to the room and knocked on the door. "Master. I've brought the guests."
"Come in."
The butler opened the door after getting the confirmation, showing a huge hall inside. The hall was filled with bookshelves, and there was a huge table in the center of the hall where the Water Lord seemed to be doing all his works. There were various books and large pieces of paper on the table, so it was clear why he needed that big table.
The Water Lord looked like a man in his early thirties. He had slanted eyes and a gentle smile. He was wearing big round glasses, making his face look innocent. His long blue hair was tied neatly on his back.
