One day, your father is a renowned diplomat. The next day, he's an infamous terrorist. When Sparrow is summoned to the reading of his father's last will and testament, the most he hoped for was a minor bequest. Instead, he inherited suspicion and accusations from the Empire that his father helped unite. Locked away in a vault are the secrets that will reveal Xavier DuMont's mysterious past and shine a light on Sparrow's future. Perhaps even the future of the entire realm. Of course, these secrets won't be obtained easily. Especially when everyone in this magical world seems so casually racist. Social dynamics in this world were already pretty strange. Somehow, Sparrow makes everything stranger.
