Lin Yun entered the Shelter Tower and discovered that the spiralling staircase was spotless. He followed the stairs up and walked for over half an hour before reaching the top floor of the Shelter Tower. He never truly entered the Shelter Tower during the end of the magic era. During that era, the mages struggling at death's door believed that entering the Shelter Tower was blasphemy and wasn't allowed.
After reaching the top floor, Lin Yun discovered that this place wasn't empty, but rather had a tightly shut room. He walked over and softly pushed the door. The door wasn't locked and slowly opened, letting Lin Yun see what was on the other side.
