The Iron War is a large conflict between the Pilkington Navy and the Onyx Watch. He probably wasted more iron than he got. During the Iron War, Robert captured a Flying Squirrel and reversed engineered it for his own squad of Squirrel fighters.
The Iron War was one of the most glorious Wars in the Pilkington Navy's time. The Iron War saw the Birth of the HMS Ragnarok, and the Flying Squirrel; two of the most vital pieces of technology in the Pilkington Navy.
