The marketplace was located near the seaside, and at first it was just a small fair where Mutators who hunted Base Variant Creatures at sea would trade supplies and catches on a temporary basis.
During that tremendous oceanic beast tide, this place served as a logistics hub between the front lines and the rear, playing a significant role.
Many wounded were treated and rested here, and numerous Mutators exchanged goods that they could use.
After the beast tide, the marketplace was preserved and became an important fairground.
Back then, the marketplace was only open on weekends, but later, as Sea Corn Base expanded, the marketplace was incorporated into the base. It remained in use as a fairground, opening daily with a scale much larger than before.
