The Marshlands, an area playable in Chapter 3-1 of Resident Evil 5, is a collection of small islands inhabited by the Sodibaya tribe. After being forced from their holy grounds, they began to migrate to the dense, crocodile infested waters of the marshes. Although they were able to slowly evolve past their primitive tribal ways, their exposure to the Type 3 Plagas by Tricell led them to revert to their old ways in a psychotic frenzy. It is assumed that after the Ndipaya are eliminated, the Marshlands are never populated again.
