The Mournland is a desolate and eerie region in the world of Eberron, known for its haunting landscapes and mysterious atmosphere. Once a thriving area, it was transformed into a wasteland after the catastrophic event known as the Last War, which unleashed powerful magic and left the land scarred. In the Mournland, time and space behave unpredictably, and strange phenomena occur regularly. The remnants of the Warforged and other creatures roam the area, while the landscape is dotted with the ruins of cities and the remnants of ancient technology. The Mournland serves as a reminder of the devastation caused by conflict and the lingering effects of magic.
