In this once-pure land, Rumors gradually spread amongst the water people, legend had it that a drop of the sea God's blood had melted into the sea and was absorbed by the original inhabitants of the land. If you capture the blood descendants of these people and consume their flesh and blood they would gain a part of gods divine power and if you eat enough people, then you could even become a high God!
No one believed it at first but under the temptation of greater powers, many were unable to resist the evil in their hearts.
At first, this rumor only spread among the higher echelon of the water city but soon enough it spread across the entire island.
Kings wanted to be Gods, people wanted to be Kings.
These original inhabitants became fresh pastries in the eyes of others.
