Anatomy & Characteristics

General Anatomy

  • Body Shape: Long, slender, serpentine body that undulates through water like a sea snake.
  • Fur: Short to medium-length fur that smooths when wet, keeping drag low.
  • Head: Sleek, elongated, hornless; reptilian ear openings sit as small slits near the jawline.
  • Gills: Discreet slits along the neck for breathing underwater.

Limbs

  • Four Legs: Pawed with separate clawed toes (no webbing), strong enough for land strides.
  • Flex: Musculature favors smooth land pacing and agile swimming kicks.

Tail

  • Length: Highly flexible tail drives steering underwater.
  • Fins: Small fin-like structures at the base for stability.
  • Fur Streamers: Long fur trails like ribbons, flowing behind the wake.

Movement

  • Swimming: Graceful lateral undulation, conserving energy in deep currents.
  • Walking: Feline-like, fluid gait when on land.

Coloration

Palettes favor smooth gradients, stripes, or patches that mirror reef and trench hues. In Athena’s case: plum, violet, lilac, and seafoam flashes with warm paw accents.

Behavior & Habitat

Thalassurnyx roam where sunlight dies—trenches, cold lakes, drowned temples. They guard submerged ruins for centuries, appearing only when sacred ground is threatened. Camouflage and patience are their first defenses; decisive strikes their last.

They favor bonds with those who respect the deep. Athena, the known Thalassurnyx of this lair, chose Kael after losing her ancient home. Her loyalty to him mirrors the species’ devotion to duty: quiet, relentless, and enduring.

"The depths hold more secrets than the sky could ever fathom. We keep them, and we keep each other."

Note: The Thalassurnyx line is closed; Athena remains its living guardian within this lair.
