Hollowdeep
Hollowdeep is an immense subterranean realm that stretches beneath vast swaths of Astraeth, a hidden world of darkness and wonder that few surface dwellers have truly comprehended. Within its boundless caverns flow underground rivers of crystalline waters, their currents shaped by geological forces that predate recorded history, while bioluminescent fungi forests cast an eerie blue-green glow across cavern floors and walls. The ruins scattered throughout Hollowdeep's depths tell stories of civilizations far older than any kingdom known to surface scholars, their architecture and artifacts suggesting knowledge and sophistication that surpasses modern understanding. Towering formations of crystal and stone create labyrinthine passages and chambers of breathtaking scale, some large enough to contain entire ecosystems untouched by sunlight for millennia. Strange and otherworldly creatures inhabit these depths—some harmless, others predatory—having evolved in complete isolation from the surface world. Among the most enigmatic discoveries are the colossal sealed doors carved into cavern walls, bearing cryptic symbols linked to the Shattered Star, monuments of such age and craftsmanship that their true purpose remains unknown. Explorers who venture deep enough to approach these doors find themselves drawn toward mysteries that seem deliberately hidden, as if something was meant to be locked away from both the surface and the depths themselves. The few expeditions that have ventured far into Hollowdeep's heart have returned with fragmented accounts of wonders and horrors, their stories often dismissed as exaggeration or fever dreams by those who remained safely above.

Landmarks
The Veil of Spores
A massive natural barrier of densely packed bioluminescent fungi that obscures a hidden passage leading deeper into Hollowdeep. The fungal growth creates a shimmering curtain of soft purple and blue light that masks the entrance to an ancient carved tunnel beyond, accessible only by pushing through the spore-laden growth which causes temporary disorientation in those who pass through it. The fungi themselves appear deliberately cultivated or magically sustained, forming an almost deliberate concealment that has protected whatever lies beyond for countless ages.
The Sunken Archive
A partially submerged ruin of worked stone and crystalline architecture half-buried beneath sediment and overgrown with luminous moss, situated on an island within an underground river where the current has carved away the surrounding cavern floor. The structure's entrance is concealed beneath an overhang of massive crystal formations that refract the bioluminescent light into disorienting patterns, making the opening nearly invisible from most angles. Within its depths, weathered stone tablets and shelves suggest it once held records or knowledge, though the rushing waters and unstable crystal formations make approach treacherous and investigation perilous.
