Path to the Mizar Oasis

From publisher blurb: It's the Arabian Nights meets A Fistful of Dollars when your party enters a desert oasis on the verge of war between two gangs who want to control its main attraction — a spring with magical waters. However, nobody is aware that powerful water elementals lurk at the bottom of the spring, and they aren't happy about humans taking advantage of their turf. Throw in a djinni and an efreeti who are best of frenemies, and it's our wildest Found by the Way yet! Path to the Mizar Oasis is compatible with Pathfinder 2E, but it includes notes for running it with Pathfinder 1E. It is published under the Open Game License and it doesn't specify a setting, so that you can integrate it into your own campaign world.
