The Rada lwa are generally regarded as being righteous, whereas their Petwo counterparts are thought of as being more morally ambiguous, associated with issues like money. At the same time, the Rada lwa are regarded as being less effective or powerful than those of the Petwo nation. The Petwo lwa derive from various backgrounds, including Creole, Kongo, and Dahomeyan. Many lwa exist "andezo" or "en deux eaux", meaning that they are "in two waters" and are served in both Rada and Petwo rituals.
