Deep within a subterranean lake, a sprawling complex of buildings lay spread out across the bottom.
Houses built from black basalt were stacked in layers, fanning out along the gentle slope of the lakebed.
The gaps in the walls were filled with bricks made from fired black clay, and the roofs were tiled with fish scales.
Fluorescent moss crept over the surfaces of the buildings, its blue-green points of light merging into a vista that resembled a starry sky submerged in water.
The most conspicuous structure in this underwater complex was a semicircular building in the central area. It resembled a tortoise shell, its surface adorned with numerous beast bones.
Inside the building, the atmosphere was oppressive.
