Primordial Wetlands VERIFIED OFFICIAL DOSSIER

Grassrivers

Southern Basin · Swamp & Mangroves (Everglades-inspired)

Grassrivers is the untamable jewel of Leonida's crown—a primordial expanse where alligators are the most famous attraction, but far from the deadliest thing lurking beneath the murky water.

Accessible primarily by roaring fanboats and lifted mud trucks, its labyrinth of mangrove tunnels shelters the Thrillbilly Mud Club, off-grid poachers, and clandestine drop sites.
