The Crystalline Caverns remain mostly intact, orbiting the remains of the elemental plane of earth. This location was critical to the success of the colony ship Home, as it housed the magical crystals now used for all sorts of magical applications on Home. Since then, the Crystalline Caverns have been left to wander the Astral Sea. It is suspected that the mining infrastructure remains intact, but the hazards of travel make exploring the Crystalline Caverns difficult.
