The caverns descend in tiered galleries connected by narrow natural bridges and smooth, fey-carved tunnels. Enormous crystal formations, some taller than the eldest grove trees, grow from floor and ceiling alike, and underground tributaries of the Moon-Lit Rivers thread through the lowest galleries.

Deep and insulated from the outer twilight, the caverns are cold and perfectly still, with no wind and only the faint hum of crystal resonance to disturb the silence. The air is dry and sharp, tasting faintly of ozone from the concentrated magical energies.

The Crystalline Cavern Depths are believed to be the oldest part of the fey domain, predating even the Glimmering Groves and likely forming the original seat of fey arcane power before the Court expanded outward. The Fey Court of the Eternal Twilight uses the deepest chambers as a repository for the physical manifestations of the Twilight Covenant's magic, making them a target of intense curiosity, and failed expeditions, by arcane scholars from other Landoryan civilizations.

It is whispered among the fey that the Crystalline Cavern Depths were not carved by geological force but crystallized whole from a single, catastrophic outpouring of raw twilight magic at the founding of the world, a moment the Court calls the First Refraction. Deep in the lowest gallery, where the Moon-Lit Rivers pool into a still black mirror, elder fey speak of the Shatter-Voice: a resonance trapped within the largest quartz pillar since before the Glimmering Groves were seeded, said to be the echo of the first word ever spoken in the fey tongue. Those who press an ear to its cold facets at the precise hour of eternal twilight are said to hear their own truest name, and some, having heard it, never speak again. Failed expeditions from mortal scholarly orders have left behind more than bones; their ambitions, it is said, have calcified into small amber-hued crystals that the Court harvests and stores among its covenant artifacts.

Daily existence in the Crystalline Cavern Depths is governed by the rhythms of light rather than sun or moon, the prismatic glow shifts in slow, chromatic tides that the fey read as hour, season, and omen alike. Covenant Wardens patrol the tiered galleries in silent rotation, pressing palms to crystal faces to sense vibrations that might betray an intruder or a crack in the magical repository below. Fey artisans known as Resonance Shapers spend their long years tuning the formations with small silver mallets, maintaining the harmonic frequencies that keep the deepest covenant chambers sealed and stable. On rare ceremonial occasions, the Court convenes in the Grand Prism Hall, the largest upper gallery, where a chosen speaker intones the Twilight Rites aloud, their voice multiplied a thousandfold by the quartz until the cavern itself seems to answer.
