The curse of Rikhill

Miguel should've known what this peace and resolution Maximus IV talking about. He only realized this when he arrived in the kingdom of Rikhill. Twenty years had been since his last visit to the said kingdom, and he could tell there were a lot of changes in this land. 

The trades were still going on with people from all across the globe docking in the kingdom's fort. Peace was still reigning over the land. Rikhill had prospered drastically even after two decades. Many goods were new to Miguel; some were new inventions that no one thought would exist two decades ago. 

Surely, humans were quick to adapt to this ever-evolving world. Their will to seek change and advancement was incomparable to other races in the world. Two decades wasn't that long for a vampire thus, it wasn't surprising these changes would take some time for them. 

If the land of Rikhill was prospering more than ever and peace still ruled over it, what was the problem?
