The Deep Solarium serves as the primary life support for the Hollow Hearth region. Beneath towering crystalline arches, bioluminescent flora creates a perpetual golden twilight. The air is thick with the scent of damp earth and oxygen rich ferns. Settlements cling to massive stalactites and the edges of nutrient rich moss fields. However, recent geological instability has begun to fracture these ancient gardens, threatening the very foundations of subterranean life for those who call the hollow home.
