      "body_structure": "Elongated, low-slung quadruped with six multi-jointed limbs optimized for vertical rock climbing and tight tunnel navigation. Vestigial dorsal membranes fold flat against the back. No tail fin; tail is short and tapered.",
      "facial_features": "Completely eyeless \u2014 scale-covered sockets. Wide, flat jaw with dense, backward-curved teeth for grip. Prominent vibration-sensing pits along the jaw, cheeks, and underside of the neck. Acid gland exits through two small ducts between the front teeth.",
      "scale_characteristics": "Dull, pale grey-white scales with a matte finish \u2014 no pigmentation. The ventral surface is slightly translucent, revealing the acid gland as a faint greenish mass behind the jaw when lit directly."

    "description": {
      "full": "The Pitcrawler is a flightless, entirely subterranean Terrestrial Wyrm endemic to the deep cave systems beneath Silgolt\u0027s eastern mountain ranges. Its wings have reduced over generations to flat dorsal membranes \u2014 vestigial structures that now serve primarily as heat-retaining panels in the cold cave environment. Its eyes are completely absent; the sockets are sealed over with thickened scale. Navigation and hunting rely entirely on a highly developed vibration sense distributed across the limbs, underside, and jaw. The Pitcrawler produces a corrosive acid spray, stored in a specialized gland behind the jaw, used both for prey capture and for marking territory on cave walls \u2014 dissolving rock to leave chemical signatures other Pitcrawlers can detect. The creature\u0027s existence was confirmed when Silgoltian mining operations broke through into nesting tunnels. Initial encounters were lethal on both sides. It is now treated as an occupational hazard in deep-mining regions; experienced crews carry specific countermeasures. Some Silgoltian cultures interpret a Pitcrawler incursion as an omen \u2014 the exact meaning varies by community, but most traditions agree it signals that something has been disturbed that should have remained undisturbed.",
