Arrin with them, a prisoner. "Out," said Sawyer thickly, his voice a hoarse croak. "Get out, fast--" Arrin's voice cracked like a silver whiplash. "Yes, run. Because they're making you, because their minds are too much for you! Run, and let them have the Citadel, and when their fleet comes, let them have the Earth!" That stopped them. The horror they felt at that thought surged up so strong that the frantic compulsion to flee lessened a little. But behind them, somewhere back in the corridors, they would be following.... Arrin raged and mocked them. "_We_ saved you from the Ei two generations ago, when Ei ships had smashed your defenses and they were ready to move in.
