As the Royal Navy and the Knights of the Round Table both devoted themselves to disaster relief efforts, the London citizens who had been victimized by the flood were gradually rescued and transported to the island where Avalon was located.
Although most people were cold and hungry, lacking food and warmth, after all of London had crumbled apart, being able to keep their lives was already a stroke of luck amidst the misfortune.
Even though the vast majority could only stay in tents made from spare sails temporarily set up by the Royal Navy, having a place to live under such circumstances, being able to light a small bonfire to warm bodies that had been frozen all night long, and then cooking up a bit of hot food to fill their stomachs, most people didn't have many more demands.
