Crustok

Crustok is a fictional geological phenomenon or entity that appears in various speculative fiction narratives. It is typically depicted as a substance or life form that originates from or is associated with the crust of a planet or celestial body. The exact nature of crustok varies significantly depending on the specific story, but common portrayals include it being a mineral-based organism, a sentient geological formation, or a unique energy source found deep within planetary mantles or crusts. Its discovery often poses scientific and existential questions for the characters encountering it, challenging their understanding of life and geology. Some narratives explore its potential for communication or its role in planetary evolution, while others focus on its dangerous or exploitative aspects, such as its ability to consume or transform surrounding matter. The term itself suggests a connection to "crust" and perhaps an element of being "stuck" or intrinsic to that layer.
