The Skycleft Howler is a cave-dwelling glider-mammal endemic to the geothermal cave systems of the Ralar Mountains on the Dark Side of VOI 700 D. Though it resembles no known Earth species, its ecological niche is similar to that of a bat. Skycleft Howlers are known for their shimmering, membrane-like glider wings and their distinctive vocalizations, which serve as both echolocation and social communication tools.

Despite their eerie howls and spectral appearance, Skycleft Howlers are shy and rarely seen. They are drawn to geothermal vents, where warmth and prey are abundant. The Zark Tribe considers the Howler a sacred omen, interpreting its call as a harbinger of subterranean shifts or volcanic changes. In Zark mythology, it is known as the “Nyaruul”, meaning “Spirit That Sings Beneath the Stone.”

• Wingspan: 1.4 meters (glider membranes stretch between elongated digits and torso)
• Body Length: 55 cm
• Weight: 7-9 kg
• Fur: Thin, heat-dissipating fur in charcoal black, mottled with glowing specks
• Eyes: Vestigial, unused in navigation
• Ears: Large, highly mobile, adapted for ultra-high-frequency hearing
• Mouth: Broad, producing long, low-frequency pulses for echolocation

• Glider Membranes: Flexible wing-like structures allow it to silently glide across open cave chambers and cliffside vents
• Bioluminescent Speckling: Glowing freckles along its limbs serve as a mating signal and as a visual deterrent to predators
• Howling Pulses: Emits howls in low frequencies that can reverberate through rock and tunnel structures for kilometers

• Armor Class (AC): 13 (natural camouflage and agility)
• Hit Points (HP): 24
• Speed: 20 ft. (land), 40 ft. (glide)

• Glide Kick: +4 to hit, 1d6 bludgeoning damage. Used during swooping passes.
• Howl Shock (Recharge 5-6): Emits a concentrated pulse of sound. All creatures within 20 ft. must succeed on a DC 12 Constitution save or be deafened for 1 minute.

• Sonar Navigation: Advantage on Perception checks involving hearing; immune to blindness
• Silent Glide: Can move without provoking opportunity attacks during a glide
• Echo Alarm: If one Howler is harmed, all others within 200 ft. are alerted via subsonic clicks

• Diet: Carnivorous; preys on insects, small rodents like the Nokari Mouse, and Bero Hiki worms
• Social Structure: Lives in roosts of 10-25 individuals in geothermal caverns
• Activity Pattern: Most active during magnetic storms and at seismic activity peaks

• Thermal Roosting: Builds nests close to hot rock surfaces for warmth and energy conservation
• Group Alert System: Uses harmonic pulses to maintain cohesion and warn of predators or seismic shifts
• Glide Ambushes: Attacks prey from above by gliding silently through cave shafts

• Mating Season: Begins during peak geothermal cycles, when prey is most abundant
• Gestation Period: Approximately 4 months
• Litter Size: 1-2 offspring per cycle

• Average Lifespan: 12-15 years (Estimation)
• Juvenile Training: Young Howlers learn to glide within three weeks of birth
• Roost Loyalty: Offspring often remain in the same roost until maturity, then migrate to nearby caverns

The Skycleft Howler can be used for stealth encounters, mysterious ambiance, or cave-based challenges. Players may need to decipher its howls to locate seismic danger or hidden geothermal tunnels. A roost of Howlers could be disturbed accidentally, leading to a frantic glide attack or a chain of alert howls warning other subterranean creatures.

• Echo Clues: Howlers may echo dangerous terrain or hint at unseen volcanic activity
• Sound-Based Puzzles: Their vocal patterns could form the basis of ancient Zark or outlaw warning systems
• Mythic Role: Tribes may ask players to protect or track a rare albino Howler, considered a prophetic sign
