Beyond the door was an even narrower passage, only wide enough for two people to walk side by side and just over two meters high.
Lynn walked through the passage, his footsteps echoing in the confined space.
He slowed his pace and remained vigilant, keeping [Analysis] active at all times.
After twenty steps, another stone chamber lay at the end of the passage.
