The Psammosere

Ruled over by the Demon Lord Furfur and home to the demons of the Mind, the Psammosere is an expansive desert where the wind is powerful enough to knock any traveler down. those who live here live near the rare oases, and are almost always connected to the sky or stars. Also notable is the Demon City of Mirage, a city spoken of in Psammosere folklore which vanishes when any creature nears its gates.
