Pillars of Glass

From publisher blurb: The site dates from at least the Bednálljan period, and may be connected with the Pariah God known as the One Other. It consists of a circle of crystalline spires, some of which have fallen (similar to Stone- henge on Earth, but with columns of natural crystal rather than crude stone monoliths). The opening to the underworld beneath reveals a circular stairway leading down into a labyrinth. It is said that at the bottom of the labyrinth is a great cavern that is filled with molten lava...
