How I Built a Magic Empire: Book 2

Our magic crystals are growing. People arrive in the village faster than we can make room for them, but at least they find plenty to do here--from building the village to guarding the border against attacks by bandits and monsters. And not just any monsters, but monsters that haven't been seen in this neighborhood before. Is that a coincidence? Or are rumors of something going on outside the borders of the Empire not just rumors? Whatever's behind them, I'll deal with it!
