Fjordback

  "aliases": [
    "Deepneck",
    "Fjord Serpent"
  ],
  "content": {
    "anatomy": {
      "body_structure": "Long, serpentine body with minimal limb development. Vestigial forelimbs function as pectoral paddles; no hind limbs. No wings. Keeled dorsal ridge runs the full length of the back, assisting stability and surface propulsion.",
      "facial_features": "Long, narrow skull with a wide jaw capable of engulfing large prey whole. Eyes are positioned high on the head for surface scanning while most of the body remains submerged. No external ear structures; vibration sensing via lateral line organs along the flanks.",
      "scale_characteristics": "Dark grey-blue on the dorsal surface, fading to pale grey-white on the ventral side. Scales are dense and tightly overlapping \u2014 resistant to cold and pressure. The dorsal keel scales are raised and slightly serrated."

      "growth_stages": {
        "juvenile": "Juveniles are occasionally seen in shallower lake inlets \u2014 much smaller and more cautious than adults",

      "lifespan": "300+ years (estimated; oldest recorded sightings span multiple generations of the same community)",

        "gestation": "Unknown; eggs have never been observed. Presumed laid in deep lake or fjord-bottom nests.",

    "description": {
      "full": "The Fjordback is a permanent aquatic wyrm native to the cold, deep fjords and ice lakes of Hjemland. Unlike all other known wyrms, it is fully committed to an aquatic lifestyle: its forelimbs are vestigial \u2014 small, paddle-like appendages used for steering at low speed \u2014 and it has no wings. Propulsion comes from powerful lateral undulation of its long, muscular body. The Fjordback is an apex predator in its waterways, hunting seals, large fish, and anything that falls or wanders within striking range of the surface. Its keeled dorsal ridge is often the only visible sign of its presence \u2014 a slow, dark line cutting through still fjord water \u2014 hence the common name. Hjemland fishing and coastal communities treat the Fjordback with a mixture of genuine dread and structured reverence. Some communities leave offerings at fjord edges before fishing season. Others regard seeing its keel as an omen, the interpretation depending on local tradition.",
