The Shattered Underworld

Ages ago, the Architects carved three subterranean realms to house the Heartstone, a crystalline engine that sustained the underground sanctuaries. When the Great Subsidence fractured the mountain, the pathways collapsed. Now young explorer Nia descends with her brass lantern to brave 30 chambers across the Verdant Sanctum, The Ember Vault, and The Frostglass Depths.
