The western corridor was considerably narrower than the enormous chamber they had left behind, but that wasn't what caught Rowan's attention.
Unlike the other passages, whose walls had been worn down by centuries of erosion, the stonework here appeared unusually precise. Each block fitted perfectly against the next, and faint markings ran along the lower portions of the walls.
Most were barely visible beneath accumulated dust, but their arrangement suggested deliberate craftsmanship rather than ordinary decoration.
"Someone went to considerable trouble building this passage," Rowan observed, crouching beside one of the markings.
He brushed away the dust and examined the shallow grooves beneath it. "These aren't ordinary carvings. They resemble directional markers, although I can't recognize the symbols."
