Adlis stone is the common name for a peculiar metamorphic rock pattern native to lowlands surrounding the Saint Montaigne Delta. First cataloged by the Geology program of the Mount Ocuma Institute for the Closed Sciences as lapidem spirans, this material is no recent discovery - chronicled in regional mythology as early as 800 A.E.D.
Found primarily within subterranean structures with high humidity and minimal exposure to light, Adlis stone’s response to environmental change has spurred much of the study surrounding the material. Presenting a subtle iridescence and porous consistency similar to Shepard’s Cheese . within natural conditions, adlis stone hardens through a rapid fossilization process within an hour’s exposure to outside conditions - quickly losing it’s characteristic iridescence and color which commonly ranges from pale viridian to midnight blue. Recent attempts to recreate and sustain these conditions through the use of man-made enclosures fine-tuned to it’s natural preference has been met only failure .
Adlis stone’s significance in the geological history of the Saint Montaigne region is largely unknown. Following the discovery of a thick sedimentary layer of chalk-like rock sandwiched between otherwise regular layers of sandstone throughout the area known as the Experimental Duchies by famed geologist Ernst Votte, this layer of rock was tested and found to match the geological profile of Adlis Stone. Privately funded research by Dr. Votte indicates that this layer is characteristic of a major environmental event or natural disaster which affected the geological profile the region between 377-388 B.E.D.
