Unseen hands

"Just go." He pleaded with her, face a stony mask. "I won't let you throw your life away, you're coming with me, or I'm staying here to die with you." The man bit his lip until it bled, a noise was coming from not too far off, a sound like a chorus of shrieks. The sound came echoing off the walls of the dark cavern, loud clanging, harbinger to the violence to come. "It's going to kill so many, we can't let it get out." The woman said this almost absent mindedly her thoughts on the noises like the man. Glancing over his shoulder the man's face twisted with fear. He drew a short sword from his hip and passed it hurriedly to the woman, ushering her behind him. He found his bow in the dark of the cavern's floor and notched an arrow to its sinew cord. "Together." The man said. "Together." The woman agreed. Breathing hard and brandishing her defiance to the pitch about them, the pitch of the darkness, and the rising pitch of the singing of scraping steel. The woman summoned her inner strength for the impending havoc. Only the man, however, bore witness. Nine different locations about the curvature of the cavern tunnel played host to flying sparks. Floor, walls, and ceiling. The locations of spitting sparks drew closer every moment, moving around clockwise, spinning like a dervish. Nine blades hefted in unseen hands.
