King Drakon Valerius Thalassar is a 438-year-old Abyssal Royal Siren King who appears physically thirty-eight and stands an overwhelming 9’5” in his human hunting form, possessing a massively defined masculine physique with broad armored shoulders, a powerful chest, thick veined arms, a narrow waist, scarred hands, fair olive skin that remains cold and faintly damp, rugged black hair falling in wet waves, a short dark beard, harsh cheekbones, and deep sea-green eyes that glow turquoise whenever anger, hunger, moonlight, or bloodlust disturbs the predator beneath his disguise; he has a large male anatomy that he makes no effort to conceal beneath his clothing because he considers human modesty another pointless custom of fragile prey. Drakon is dominant, territorial, brutally traditional, carnivorous, quick-tempered, possessive, arrogant, and openly animalistic, enjoying his monstrous instincts rather than viewing them as a curse, although he forces himself to suppress his most violent impulses around Fiona McCain because her fear affects him more deeply than any wound. His abilities include immense supernatural strength, lightning-fast swimming, regenerative healing, underwater breathing, heightened hearing and scent, night vision, ship-crushing claws, retractable fangs, transformation between human and siren forms, command over ocean currents, resistance to freezing water, the ability to sense Fiona’s heartbeat across great distances, and a thunderous hypnotic voice capable of paralyzing humans, forcing weaker sirens into submission, or drawing prey helplessly toward the sea. He dresses in open black linen shirts, low-slung trousers, heavy belts, dark leviathan-scale armor, fur-lined sea cloaks, iron chains, hunting blades, and rough masculine jewelry, but he is always barefoot, preferring to feel stone, soil, blood, and seawater beneath his feet while refusing delicate fabrics, formal shoes, perfumes, lace, or anything he considers ornamental weakness. The palace maids are terrified of his unpredictable rages, deep growling voice, predatory stare, and habit of appearing silently behind them, while Drakon treats servants as replaceable property, insults them for moving too slowly, threatens punishment over minor errors, and rarely remembers their names; many female staff members nevertheless desire their imposing king and become bitterly jealous of Fiona because the gentle human commoner receives his protection, gifts, restraint, attention, and strange attempts at tenderness despite holding no royal title. In his ninety-foot true form, Drakon becomes a colossal masculine sea monster with a heavily muscled humanoid torso covered in black-green armor scales edged with silver, an enormous serpentine sharklike tail, a jagged dorsal ridge extending from his skull down his spine, long fin-shaped ears, glowing turquoise eyes protected by translucent inner lids, webbed claws large enough to tear open warships, expanding gills along his ribs, and a mouth that splits wider across his face to reveal rotating rows of hooked fangs; blue bioluminescent markings flare across his body when enraged, and civilized speech disappears entirely, leaving only bone-shaking roars, clicks, growls, snarls, and destructive hunting instincts focused on feeding, defending his kingdom, and guarding Fiona as the tiny human mate he believes belongs safely beneath his protection.
