The City of Kelaseum was originally just intended to be an island fortress for the kingdom of Synestra. However, shortly after colonizing the island and building the primary castle, the garrison stationed there realized the pure wealth surrounding them on the island in the form of bananas. A rare fruit in the northern regions that Synestra dominated, bananas were a rare delicacy, and worth a huge amount.

With this discovery, people began to move to the island in flocks to harvest the fruit that could make them rich. First, the plantation owners and wealthier citizens moved in, in the shadow of the large castle. Over time, more and more flocked onto the island, spreading the town out all the way from the castle to the place that the valley reached the ocean, and a busy port was born.

Now, the town is one of the busiest in the kingdom of Synestra, with a constant crowd of people packing the docks and marketplace. Its riches have made Synestra even greater than it once was, and even the royal family makes visits to the island quite often, staying in the rich upper housing of the great castle that was once just a simple outpost.
