Jin was walking down a dark staircase. There was a mossy stone ceiling, from which water dripped and fell down to his head. There were sporadic torches on the cracked, rough stone walls; crafted almost exactly like those from the Middle Ages. And then there was the temperature.
Even with flames of the torches at both sides; Jin found the temperature extremely cold—almost unbearable. He felt as though he was in a refrigerator. He wasn't. But he was in a powerful Wizard's house.
As soon as Jin took the last step down. He felt something. He quickly stopped, not walking another step forward. Kai, however, continued walking. It looked as though he walked through a clear, shifting wall, and disappeared. He was supposed to be right there in the same room as Jin, but he was not.
