What is going to happen to the Aurorans?""They are prisoners of war," Albion said. "I should imagine they will be set to work at the base of the Spire."Grimm tightened his jaw. "No, sir.""No?""No, sir," Grimm said. "I've seen that place. You might as well tie a noose around their necks and stand them on blocks of ice, if you want them to die a slow death. It will be cleaner.""I'm not sure why this concerns you, Captain," Albion said."Because they surrendered to me," Grimm said. "They gave me their parole, sir. They could have fought on with no real chance of victory, and it would have been bloody. But that surrender saved blood and lives of Albions and Aurorans alike. I will not see Captain Castillo repaid with such churlish treatment.
