Walking out from the 'dressing room' still did not lead to the residential area. Instead, it led to another large area that bore similarities to a train station platform. The shape of this area was very much similar to the columned area that they had passed earlier. It was possible that the two areas were mirror images of each other.
When they reached this point, the surrounding air was already fresh enough to allow people like Hank to breathe without the aid of the protective gear. After walking past this area and a twisting tunnel of sorts, their eyes opened, and the three finally reached the inner sanctum of the Village of Heavenly Blessing.
