Mabar

Early scholars studying reports of Mabar concluded that it was the Plane of Darkness—that this physical property is its defining concept. However, the plane’s eternal gloom is just a symptom of its true nature. Even the brightest day eventually ends in darkness, and Mabar embodies this idea. It’s the shadow that surrounds every island of light, patiently waiting to consume it. It’s entropy, despair, and loss. This isn’t the place where the souls of the living go after death, but rather, it’s the plane of death itself—the hunger that consumes both light and life. Esut's patron, the Queen of All Tears rules The Last Desert in Mabar. Source
