The Glowfin Ray is a flat, cartilaginous predator native to the volcanic shallows of Ralar Bay on the Dark Side of VOI 700 D. It is named for the distinct bioluminescent streaks that run along the edges of its fins, which pulse in rhythmic patterns while hunting.

The Glowfin Ray is a top-tier predator in the geothermal ecosystem, known for ambushing prey from beneath sandy vent deposits and stunning targets with a sudden flash of light.

• Size: 1.5 to 2 meters wingspan
• Weight: 80-110 kg
• Body Shape: Flat, manta-like with broad fins and a tapered tail
• Coloration: Charcoal gray with glowing blue fin-linings
• Eyes: Reduced; relies mostly on vibration and light sensitivity

• Capable of emitting controlled pulses of bioluminescent light to disorient prey
• Tail equipped with a hard, blunt spine used in ramming attacks
• Lays dormant beneath sediment, rising with explosive force when prey is near

• Armor Class (AC): 14 (tough skin and speed)
• Hit Points (HP): 45
• Speed: 50 ft. (swimming), 10 ft. (burrow in sand)

• Bioluminescent Pulse: Creatures within a 15 ft. cone must succeed on a DC 14 Wisdom save or be blinded until the end of their next turn.
• Ram Strike: +6 to hit, 2d8+3 bludgeoning damage

• Flash Ambush: When hidden in sand, gains advantage on initiative and its first attack.
• Light Tracker: Can sense movement from any bioluminescent organism within 60 ft.

• Diet: Carnivore; feeds on Deepfish, crustaceans, and smaller rays
• Social Structure: Solitary hunter
• Activity Pattern: Nocturnal ambusher, active during thermal surges

• Camouflages beneath geothermal sediment to avoid detection
• Uses fin light pulses to confuse or lure bioluminescent prey

• Mating Season: Unknown; believed to be solitary except for mating
• Birth: Ovoviviparous; gives live birth to 1-3 offspring per cycle

• Total Lifespan: Estimated 20+ years
• Juvenile Phase: Young rays remain hidden in shallow tidepools until strong enough to hunt

Glowfin Rays are a threat-level encounter in geothermal zones, perfect for stealth-based or horror-themed aquatic adventures.

• Vent Guardian: A ray might defend a sulfur pool suspected of hiding ancient tech or forbidden relics.
• Unexpected Predator: The glow of its fins might first appear beautiful — then deadly.
