Taking a deep breath, he walked forward.
He walked for what felt like several minutes, the corridor unwinding before him with no sign of variation. The walls remained the same height. The floor stayed the same width. The light retained the same low, ambient blue glow, despite having no visible source.
Then he arrived back at the entrance.
He stopped. Slowly, he turned in place.
The corridor stretched out before him once again, in the very direction he had just come from. The same silent stone. The same unchanging walls. The same impossible extension into a distance that should not have existed inside a passage of any reasonable length.
He tried again. This time, he walked farther and and faster.
Several minutes later... He arrived back at the entrance.
'What the fuck is going one?!' A frown formed on his face.
He turned around and walked the opposite way. This time, he didn't return to the entrance.
