A room up ahead

The two women cautiously make their way forwards through the tunnel, which curves slightly to the right, continuing to arc until the entrance is no longer visible behind them. Up ahead they spot an archway, and a chamber behind it, about 30 by 30 feet.

”What’s that?” Diana whispers, indicating a small light hovering across the room. It almost looks like a firefly, exuding a bright greenish glow. ”Looks like a glowy bug” Tyra remarks.

They inch forwards to the archway. The chamber is empty, apart from the firefly circling the room, but there is a doorway on the other side followed by another corridor.
