Upon placing your [Ethereal Soil] here 3 soil mounds and 3 earthly podwalkers spawn. You have to defeat each earthly podwalker over the corresponding mound. Repeat this process with 3 waters of Awuidor and 3 flits of radiance - Passing the test severs the plane's link to the Ethereal Soil, so that you can take some [Severed Ethereal Soil] needed for the Council of Soil.
