Thunder in the Stone Canyon

I slipped through the cracked doorway straight into an immense concrete canyon! The air was cool, carrying the scent of raw stone. I stomped my foot against the hard step. BOOM! The sound cracked like thunder, bouncing off sheer walls and rocketing up into the dizzying ceiling! Intoxicated by this newfound acoustic power, I charged down three massive stone ledges, hammering my heavy claws down in a fierce, rhythmic march! BOOM-CLACK! BOOM-CLACK! The entire vertical shaft answered my cadence with a roaring, metallic echo! This cavern of steps belongs to me!
