Whispers in the Nsi Wastes

Deep in the jungles of Chult lies a blighted swamp land called the Nsi Wastes. The sickness of the land spreads with the passing of every year and has begun to threaten the aarakocra of Kir Sabal. An evil lives in the ruins of Ras Nsi's fortress, which once stood on the backs of a dozen giant undead turtles and has spent the better part of a century sinking into the muck.

This supplement to Tomb of Annihilation expands on the location the Nsi Wastes. It is meant to make this location more exciting and manageable for both the DM and the players.
