South Exit: Route 108

Sea Mauville used to be a large scientific research platform off of Route 108 which used to be staffed by Captain Stern and Professor Cozmo's father, among many others. It closed down following the failure of the New Mauville project and ended up being dilapidated, with half of it sinking underwater. Many trainers use the area now to train or be hidden away.
