An intricate network of tunnels, dimly illuminated by iridescent gemstones that do not tolerate natural light. The passageways connect all landmarks of the wastes, at least to those well acquainted with its labyrinthine corridors.

An abandoned town in the throes of gale-force winds and shifting currents, swallowed by day and unearthed by night. The dunes undulate incessantly, as though riding lunar tides, sweeping to and from the abandoned settlement; certain Hollow have divined, and exploited the sand's ebb and flow for shelter.

A lowland swamp teeming with lesser Hollow. A thin smog of noxious fumes, benign to Wasteland natives and mildly hazardous to the rest, lingers near the surface. The miasmic swamps sustain the wastes' most diverse assortment of organisms, from flora to fauna; hardwood mangroves bear host to a wealth of opportunistic Hollow, and the wetlands support a loathsome menagerie of gnarled plants.

The mountainous region composed of smaller mountains which in turn skirt within the boundaries of the great, mountainous regions surrounding the world. Though these areas are less corrupted than the rest of the Wastelands, the mountains beyond are veritably untouched by Hollow or otherwise, and vanish high into the sky, impassible barriers to what lies beyond.
