   Summary

   The "necro crystal" (or corpse crystal) refers to Vivianite, a rare iron phosphate mineral famous for growing directly on decaying organic matter, such as ancient fossils and human remains. It is formed when phosphorus from decomposing bones reacts with iron and water in oxygen-poor environments.

   OR: Grace dies from old age, but comes back eridian.
