A region of dense, treacherous jungle along the Rain Wild River, where the remnants of Elderling civilisation lie buried. The Rain Wild Traders live in tree-cities above the acidic river, mining Elderling artefacts. Prolonged exposure to the environment (and the buried memory stone) causes physical changes - scales, claws, and other alterations. The Rain Wilds are where the dragon cocoons are found and where the journey to restore dragons begins.
