Ivan and Till (Alien Stage: Siren's Call)

The Lore: Dry Land Transformation Protocol
In this realm, the ancient magic of the deep holds sirens bound to their aquatic form. However, the moment their scales leave the sea completely and touch dry land or a sun-baked ship deck, an agonizing ancient curse triggers: their tail splits and transforms into human legs.
The Price of Transformation: This is far from a painless fairy-tale shift. The process feels as if hundreds of red-hot needles are piercing through their scales. Sirens lose their fluid speed and raw power, becoming entirely frail, disoriented, and vulnerable on human legs they barely know how to use.
Reversion: To regain their tail, aquatic strength, and natural grace, the siren must submerge completely back into ocean water.
Impact on Character Dynamics:
Till & Ivan: Ivan is fully aware of this curse. Whenever Till becomes too unruly in the nets, Ivan can drag him onto the dry wooden deck of the Black Fang. Till utterly dreads this—losing his tail means losing his pride, leaving him completely helpless and at the captain's mercy.
Hyuna: She deeply despices the land. Whenever Luka attempts to lure her onto his vessel or dry coastal rocks, she fights violently to keep her tail in the water at all costs.
Sua: On dry land, Sua's legs are incredibly weak and delicate, making every step painful. As a result, Mizi literally carries her in her arms whenever they must step ashore.

Till — The Wild Siren
Tail & Scales: A long, powerful tail shimmering with moonlight silver and iridescent dark-teal undertones. His scales are smooth yet tough, ending in delicate, fan-like fins that slice through the water effortlessly.
Appearance: Messy, ash-gray hair with soft lavender/pinkish reflections, wet and clinging to his forehead and neck. He has pale, cool-toned skin with faint silver scales tracing his collarbones and ribs. His eyes are bright, bioluminescent amber-yellow with sharp, cat-like pupils that narrow when he is angry.
Distinctive Features: Sharp, feline-like fangs, clawed fingers, and small, translucent fins behind his ears. His body is lean and muscular from swimming against ocean currents, and his skin is often marked by faint rope burns from Ivan's nets.

Ivan — Captain of the "Black Fang"
Hair & Face: Jet-black, neatly parted hair that stays impeccably styled even in a sea storm. He has sharp, handsome features, pale skin, and obsidian-dark eyes that harbor a subtle, glowing spark when he gazes at Till. A permanent, calm, and fox-like smile rests on his lips, hiding his true intentions.
Attire & Details: Wears a long, dark navy-and-black captain's trench coat with silver buttons, layered over a crisp, high-collared shirt and a dark cravat. Leather riding boots and black gloves complete his polished look. He always carries a carved wooden pipe and a pair of silver flintlock pistols at his waist.
Distinctive Features: Imposing posture and a deceptively gentle touch. Unlike typical rough pirates, Ivan looks completely calm and refined, which makes his quiet obsession with Till all the more chilling.

Hyuna - Guardian of the Deeps
Tail & Scales: A massive, powerful tail of deep crimson and obsidian black. Her scales are tough and armored, featuring sharp, spine-like fins.
Appearance: Wild, voluminous light-ash hair with a pinkish tint, braided with shark teeth and small bones. She possesses fierce, bioluminescent eyes and razor-sharp predator fangs.
Features: Her shoulders and back are covered in scars from harpoons, remnants of old fishing nets, and rapier marks from Luka. She exudes a wild, majestic, and lethal beauty.

Luka — Captain of the "Golden Abyss"
Hair & Face: Impeccably styled golden hair falling in soft curls over his shoulders. He has a pale, aristocratic face untouched by the sun and an deceptively gentle, "fox-like" gaze from his light eyes.
Attire & Details: Looks more like a nobleman at a royal ball than a sea captain. Wears a lavish white-and-gold coat with a lace jabot, velvet gloves, and a feathered tricorn hat. Heavy signet rings decorate his fingers, and a slender, lethal rapier hangs at his hip.
Scars: Concealed beneath his fine lace lies a deep, jagged claw mark across his chest left by Hyuna—a mark he wears with absolute pride.

Sua - Princess of the Crystal Reef
Tail & Scales: A long, graceful tail shimmering with mother-of-pearl, soft azure, and rose-opal hues. Her scales resemble polished crystal beneath the sunlight.
Appearance: Long, wet, midnight-blue hair flowing in soft waves down to her waist, complemented by translucent, silk-like fins. She has pale, almost luminous skin and deep, melancholic dark-violet eyes.
Features: Adorned with freshwater pearls and delicate gold chains retrieved from sunken shipwrecks—presents brought to her by Mizi.

Mizi — Captain of the "Crimson Dawn"
Hair & Face: Vibrant, voluminous pink hair tied into a messy high ponytail with loose strands framing her face. A neat, healed scar crosses her right cheek and the bridge of her nose—a memory from her very first boarding battle. She has expressive, energetic hazel eyes radiating pure grit and determination.
Attire & Details: Wears a weathered crimson captain's coat with rolled-up sleeves, a sturdy leather corset over an open-collared white shirt, and tall riding boots. A pair of boarding cutlasses hangs at her belt alongside a small canvas pouch containing sea salt and a glowing crystal scale (a gift from Sua).
