On a broad, flat-topped rise stand over a dozen structures which look like the skeletons of some great monoliths. The tallest of them rise to well over a hundred feet in height.
Near the outskirts of the group of structures, a large metal sign can be found (it once stood upright upon two posts, then was almost wholly buried within the earth, and now dug out and lies upon the ground). The sign is quite faded, but can still be read. Upon it is a simple, stylized image of an orange-red sun setting over green hills, and two words: Sunset Heights.
The structures are quite regular in placement and internal arrangement. They have rectangular footprints, of up to 200 feet across, and they are constructed in the forms of grids of massive pillars which support evenly spaced horizontal planes.
Close examination reveals that these were clearly buildings meant for humanoid habitation. The exterior walls are almost entirely destroyed (lending the buildings their skeletal appearance), but vague suggestions of doors, windows, balconies, etc. can still be seen. Sand and earth have buried what were once the ground floors of the buildings, which, evidently, used to be even taller than they are now.
Within the buildings are corridors, rooms, stairwells; even the smallest of the structures seem to have been capable of housing hundreds of inhabitants. The structures are damaged by time, and do not seem entirely stable. Some of the floors are treacherous, with chunks of flooring being wobbly or cracking; many walls have large cracks running through them, and the entire structure sometimes emits worrying creaks and groans.
The construction of the buildings is quite alien, both in techniques and in materials. Something like stone can be seen in exposed parts of walls; great beams of what looks like steel; other materials even less familiar. Within the rooms on the upper floors can be found furniture, which is similarly baffling: familiar in form and purpose (chairs, tables, couches, beds, dressers, cabinets, and the like), but in unfamiliar styles, and of unknown composition (there are items that have the appearance of wood, but show no signs at all of rot; metallic parts that haven’t rusted in what must be centuries; and parts of an even more exotic make-up).
On the lower reaches of the buildings are signs of squatting by savage humanoids (gnolls and goblins)—remnants of cooking fires, trash piles, markings on walls, old bones. Even these are very old, however—decades, if not centuries. There is no sign of any more recent inhabitation.
