Superposition: a Lexicon game
Astral Granite is a construction material generally used in the foundations of intruding architecture. The artificial material looks and feels like dense stone however, unlike native crystalline structures, Astral Granite can spontaneously reform structural cohesion after fracturing. This extraordinary feature is likely responsible for the relatively superior survivability of many large buildings which intruded, when compared to the destruction of the native buildings which were intruded upon. A dark energy signature has been detected, but scientific examination is hampered by a lack of material. A few pieces of Astral Granite which were severed at the physical edge of the intrusion were not retracted. More unidentified samples may remain among the rubble cleared from near the boundaries of the incident, and in the troves of sparklecombers.
