Fairy fort / earthen ringfort in Lismire

Thirty feet of rope stretched across the chamber, tying the red tower to the black one. I pulled the rope until my arms burned, but the chamber did not move. I pulled until the rope cut through my palms. The red tower cracked. Behind the crack sat a smaller chamber, and inside that chamber sat a woman made of red light. She held a knife. She cut the rope in two. The chambers fell apart like a house of cards. I stood in the danger room with blood on my hands and no tower above me. The woman disappeared. The red marks vanished from the wall. The game had not tested strength. It had tested whether I would take the chamber from the person inside it. I pulled from both ends. She lived in one end. I should have seen that before I pulled.
