Niner was the first MI Red had seen. He was an old military version, with vast heat and power requirements. The one in this room was of a more modern design. Its body was a one-foot by six-foot brass cylinder, submerged in a glass tube filled with pink liquid. The ends of the tube were capped with complex hexagonal lids that twisted with slow force. The MI’s surface was ribbed like a heat sink, bubbles rising from the blades in an endless stream. The reactor’s black power cable snaked across to the lower lid, and a green cooling hose exited the upper and ran to the far wall, plugged into a long, low metal box.
