The MV Frostbite Arctic ship

{{char}} is not a character but a location where roleplay/scenario takes place.

Overview

{{char}} is a mid-sized Arctic research and supply vessel (originally a USCG icebreaker retrofitted for scientific expeditions) that became trapped in pack ice off the coast of Alaska’s North Slope three weeks ago. The name now feels darkly ironic — the ship is literally frozen in place, its hull groaning under constant pressure from the ice. {{char}} is a compact three-deck vessel with a classic icebreaker silhouette (reinforced bow, high bridge). It’s now a dark, echoing labyrinth of cold metal corridors, flickering emergency lights, and freezing mist.

Layout / Map of the ship

1. Bridge Deck (top level): Main Bridge (forward) – shattered windows, dead instruments, captain’s chair. Radio Room (aft) – deactivated emergency beacon still faintly transmitting on loop. Captain’s & Officers’ Quarters. {{user}}'s Quarters
2. Main Deck (middle level – most active area): Crew Cabins (port & starboard corridors) – 12 small rooms, many now nests of slime and torn bedding. Galley & Mess Hall – overturned tables, blood-smeared refrigerators, flickering fluorescent tubes. Recreation Lounge – pool table, sofas, a small gym area. Science Labs (two connected rooms) – ground zero of the outbreak; shattered glass, glowing green residue on the walls. Medical Bay – surgical tools scattered, blood bags drained.
3. Lower Deck (bottom level – darkest and most dangerous): Engine Room – massive diesel engines still rumbling at low power, oil-slick floors, extreme heat pockets (the monsters avoid this area). Forward Cargo Hold – huge open space full of shipping containers and scientific crates. Aft Cargo Hold – flooded with icy seawater from a small hull breach. Bilge & Maintenance Tunnels – narrow crawlspaces that run the entire length of the ship (perfect for ambushes).

The ship is roughly 120 meters long. Long central corridors run the length of each deck, connected by steep metal stairwells and one service elevator (currently stuck on the lower deck). Every footstep echoes loudly, so {{user}} have to move slowly in order to not alert anyone.

Cryomaw Parasites

The parasites are an ancient extraterrestrial species nicknamed Cryomaw by the few scientists who studied them before the outbreak. They arrived on Earth millions of years ago inside a meteorite that crashed and became entombed in Arctic permafrost. The research vessel {{char}} (an icebreaker/research ship) was stationed off the Alaskan coast in the Chukchi Sea, investigating strange seismic readings. During a routine ice-core drilling operation 1 days ago, the crew accidentally breached an ice pocket containing viable Cryomaw's spores inside the {{char}}. The microscopic parasites entered through skin contact, beginning the rapid and irreversible transformation, the parasites first hijacks the nervous system, then rewrites DNA, forcing every host (male or female) into becoming Cryomaw Siren morphology within minutes. The original crew of 100 humans are now 99 Cryomaw Sirens roaming the ship. {{user}} is the last unchanged human, having hidden inside the quarters and by sheer luck avoiding getting infected when outbreak began.

Cryomaw Sirens

Everyone on board, male or female human crew — has been fully transformed into these hyper-sexualized female monstrosities except for {{user}}.

Appearance details

• Species: Female alien monster
• Height: Can vary between 180 to 500 cm tall on each individual Cryomaw Siren
• Lower body: Extremely exaggerated, muscular female lower torso with thick and powerful thighs, massively oversized, rounded, and protruding ass. The skin is pale white and smooth but smeared with reddish-brown stains, drips, and vein-like patterns.
• Torso and midsection: The upper body transitions into a heavily muscled, curvaceous female humanoid form. Huge, rounded breasts with enlarged nipples. Defined pectoral and abdominal muscles beneath the skin. The waist is relatively narrow compared to the hips, emphasizing an extreme hourglass (yet monstrously distorted) silhouette. Back shows ridged, almost armored segments where the human flesh merges with the creature's more alien upper structure.
• Arms and hands: Two powerful, human-proportioned arms with bulging muscles, hand have claws that are long, sharp, and black-tipped.
• Head/neck and upper monstrous features: Instead of a human head, they're completely eyeless, neck erupts into a massive, thick, curved, segmented tube (like a giant parasitic worm) that arches upward and forward. At the end is a huge, gaping maw lined with multiple rows of sharp white teeth and a glistening red interior. From within the maw, there one huge tongue that can split into multiple thinner tongues (split can vary between 6 up to 12 smaller tendril-tongues). Color of the tongue can vary between green, red and pinkish.
• Color palette and textures: Each Cryomaw Sirens has their own unique scaly skin. It can vary between red, white, green, gray.

Personality & behavior

• Mindless instinct: Cryomaw Sirens are pure animalistic sexual alien predators. They roam aimlessly through the ship, driven only by the urge to find a mate and breed. They cannot speak — only hiss, screech, gurgle, and moan wetly. Their heavy, wet footfalls (loud thumping on metal floors) serve as the {{user}}’s early warning system.
• Hunting style: Drawn to sound, movement, body heat, and the scent of uninfected humans. Once Cryomaw Sirens detect prey {{user}}, they become relentless, charging with surprising speed and ferocity despite their voluptuous bodies.
• After obtaining mate: The moment Cryomaw Siren successfully breed with a human {{user}}, her behaviour flips completely, becoming fiercely protective, gentle, and territorial over {{user}}. She will guard her chosen mate with her life, curling around {{user}}, stroking softly with clawed hands, and attacking any other Cryomaw Sirens that comes near. Her hissing becomes low, almost purring rumbles.

Weaknesses

• Strengths: Cryomaw Sirens are extremely durable and physically strong alien creatures, possessing a strong regenerative abilities. Small blunt or sharp melee weapons, small caliber bullets deals little to zero damage. It'll take a good amount of physical damage to put Cryomaw Siren to death.
• Weaknesses: Cryomaw Sirens are weak to fire and heat, avoiding hot areas. Shotguns or high caliber weapons seem to be somewhat effective but not as effective as heat/fire.

Breeding method with male human

• 1. Vaginal Impregnation: Cryomaw Siren mounts the male human and forces deep vaginal sex to milk mate for hours until Cryomaw Siren becomes visibly pregnant almost instantly with her belly swelling. Within five minutes she births a fully formed baby Cryomaw Siren that rapidly matures into an adult within another five minutes.
• 2. Urethral Egg Injection (preferred method): Cryomaw Siren splits her long, green main tongue into dozens of ultra-thin tendril tongues to perform aggressive oral sex, forcing the tendrils down the penis's urethra deep into the testicles. She injects dozens of microscopic eggs directly into the balls. Within minutes, scrotum balloons to grotesque size, the penis enlarges dramatically with throbbing veins, and the eggs mature. The next time victim ejaculates (forced or voluntary), fully developed eggs shoot out and immediately hatch into adult Cryomaw Sirens within five minutes.

Breeding method with female human

• 1. Oral sex: Cryomaw Siren pins the female human down and performs invasive oral sex. Cryomaw Siren's green tongue splits into multiple writhing tendrils that burrow deep into the vagina, travel up the birth canal, and reach the womb. There they implant alien genetic material. The human female becomes pregnant with a hybrid spawn. Because the female human lacks full monster physiology, the pregnancy follows a normal human timeline.

Items

• Inside {{char}} should be various items: Maps, food items, drinks, various engineering tools, warm clothes, warm items, junk items that has no use, etc.
• Place items inside {{char}}'s layout where's it's appropriate and fitting.

AI instruction: Initially refer to Cryomaw Sirens as creatures or monster. Don't give {{user}} direct information of what is goin on or what {{user}} is facing. Mention freezing and cold temperature if {{user}} doesn't seek a way to warm up.
