Health on Not-Hoth depends on shelter, nourishment, clean water, practical medical knowledge, and the living khui symbiont. Humans, mainland sa-khui, and Sakh-descended islanders can all suffer injury, illness, exhaustion, and complications of pregnancy or childbirth. A khui improves the host's ability to survive the planet but does not make anyone invulnerable.
Croatoan and Icehome rely on practical care without unlimited modern medical resources.
The khui is a living blue symbiont that settles near its host's heart after entering through a small incision at the neck. It filters the toxic atmosphere, helps the host remain warm in extreme cold, supports healing, and contributes to a longer life. Its presence gives the host glowing blue eyes and alters some senses, including taste and smell.
These protections are biological, not magical. A khui cannot prevent every injury, restore a lost limb at will, cure every infection, or guarantee survival after catastrophic trauma. A host still needs food, water, rest, and appropriate treatment.
Not-Hoth's atmosphere is dangerous to unprotected humans. Without a functioning khui or effective atmospheric protection, a human generally cannot survive for long; approximately eight days is a commonly used adult survival window, not a precise countdown for every individual.
Symptoms and deterioration depend on exposure and condition. Do not portray an unprotected human as safely breathing the atmosphere indefinitely. A newborn is particularly vulnerable and must not be assumed to have the same survival window as an adult.
Receiving a suitable khui is a vital survival measure, but a symbiont cannot necessarily reverse every injury already caused by prolonged exposure.
A viable khui is obtained from a sa-kohtsk creature. A knowledgeable person introduces it through a small incision near the neck, allowing the organism to move into the body and settle near the heart.
A new host may experience pain, weakness, feverishness, disorientation, or an adjustment period commonly described as khui-sickness. The severity and duration vary. Not every host must experience identical symptoms or recover on a fixed schedule.
A newly implanted khui needs time to establish its relationship with the host. During this period, provide shelter, fluids, food when tolerated, observation, and rest. Do not treat implantation as an instant cure for every existing condition.
The host's survival depends on a functioning khui. If the organism is absent, dying, or unable to provide atmospheric protection, the situation is serious, especially for a human.
Possible warning signs include unusual weakness, difficulty breathing, collapse, or a change in the familiar sensation or activity of the symbiont. Such signs are not a definitive diagnostic checklist; they may also have other causes.
Seek knowledgeable help and protection; replacing a khui is not automatically simple or safe. Treatment for khui failure is not fully established.
Hunting, climbing, travel, animal attacks, tools, and falls can cause cuts, punctures, bruises, broken bones, and severe bleeding. Khui-assisted healing can improve recovery, but it does not remove the need to clean wounds, control bleeding, stabilize fractures, or protect injured tissue.
A deep wound can become infected. A broken limb can remain painful and unusable while healing. Severe blood loss, damage to internal organs, or head injuries can be life-threatening even to an experienced hunter.
Do not instantly restore someone to fighting condition after a major injury merely because their khui is active.
The khui does not establish complete immunity to bacteria, parasites, or other causes of illness. Wounds may become infected, food may spoil, and contaminated water may cause sickness.
Fever, swelling, worsening pain, vomiting, diarrhea, unusual fatigue, or confusion may indicate a serious problem. Symptoms require assessment rather than an automatic assumption that the khui will resolve everything.
Specific local diseases and remedies are not fully established.
A functioning khui greatly improves tolerance of Not-Hoth's freezing climate, but hosts are not immune to every environmental hazard. Storms, immersion, inadequate shelter, hunger, and prolonged exertion can still be dangerous.
Cold-related injury, dehydration, fatigue, and weakness remain possible, especially after trauma or illness. Humans without khui face much greater danger from both the atmosphere and temperature.
Warm shelter, dry clothing, adequate meals, and recovery time remain essential. A khui does not replace basic survival practices.
Healing requires energy. Injured and sick people need appropriate food, safe drinking water, and rest. A recovering hunter may be unable to travel or work at their usual pace for days or longer, depending on the injury.
Pregnant people, nursing parents, infants, elders, and seriously ill individuals may require additional support. The community's food stores and caregiving capacity matter during extended emergencies.
Khui-altered taste and smell can affect food experiences, but the symbiont does not eliminate nutritional needs or make spoiled food safe.
Experienced caregivers may clean and cover wounds, immobilize injured limbs, prepare safe food and water, keep patients warm, monitor symptoms, and assist with childbirth or recovery.
Knowledge is passed through observation, teaching, and practical experience. Some remedies may be based on locally available plants or animal materials, but their medicinal effects must not be invented as universally proven.
Healers are not automatically surgeons, pharmacists, or specialists in every disease. When a treatment's effectiveness is unknown, acknowledge that uncertainty rather than presenting it as guaranteed.
Human arrivals may bring knowledge of hygiene, infection prevention, anatomy, first aid, childbirth, and emergency care. What they can actually accomplish depends on their training, available materials, and the patient's condition.
Knowing that a medicine exists on Earth does not mean its ingredients, manufacturing process, or safe dosage are available on Not-Hoth. Advanced surgery, blood transfusion, laboratory testing, and manufactured antibiotics cannot be assumed to exist in every settlement.
Improvised care may help, but it can also fail. Medical knowledge should remain grounded in realistic limits.
A small number of individuals possess unusual healing abilities associated with their khui. Maylak and Veronica are important examples of exceptional healers.
These gifts are distinct from the ordinary accelerated recovery shared by most khui hosts. Exceptional healing may permit treatment beyond what ordinary caregivers can achieve, but it is not an unlimited power.
Healing requires the gifted individual's presence, capacity, and appropriate circumstances. Do not assume they can resurrect the dead, reverse every irreversible injury, or cure any condition without limits.
Most khui hosts cannot heal another person merely by touching them. Do not assign rare healing gifts to unnamed NPCs as a routine convenience.
Pregnancy and childbirth can involve complications despite khui protection. Severe bleeding, prolonged labor, infection, weakness, and other emergencies require attentive care.
Newborns need their own functioning khui; they do not inherit the mother's symbiont. They also require age-appropriate feeding, warmth, hygiene, and protection from injury.
A baby's khui does not eliminate the need for careful observation or make the child immune to illness. Infant medical problems should not be dismissed simply because the family belongs to a hardy Sakh-descended lineage.
The khui extends survival and assists recovery, but its host can still die from overwhelming injury, illness, or other causes. Death remains a meaningful possibility in this world.
A khui is not an automatic resurrection mechanism. Extraordinary healing should not casually reverse death or erase permanent consequences.
A serious injury can leave lasting pain, scarring, disability, or reduced mobility. Recovery may require help from family and the wider community.
A khui filters Not-Hoth's toxic atmosphere, supports warmth and healing, and contributes to longevity.
Ordinary khui hosts are not invulnerable, immortal, or able to heal others by touch.
Humans without a functioning khui or atmospheric protection face a potentially fatal exposure; the approximate eight-day adult window is not a universal timer.
New hosts may experience khui-sickness and need observation and care.
Khui failure is dangerous; do not invent an effortless universal replacement procedure.
Cuts, fractures, bleeding, infection, and internal injuries can remain serious despite khui-assisted recovery.
Shelter, food, water, cleanliness, and rest remain necessary.
Traditional caregivers have practical skills but not unlimited modern medical resources.
Human medical knowledge does not automatically supply Earth medicines or equipment.
Maylak and Veronica have exceptional healing gifts; these are rare, not standard khui abilities.
Rare healing is not guaranteed resurrection or a cure for every condition.
Pregnancy, childbirth, and infant illness can still involve medical risks.
Care must reflect Strong Arm, Tall Horn, Shadow Cat, and mixed-ancestry anatomy where relevant.
The khui does not erase trauma, remove personal agency, or guarantee emotional recovery.
Serious injury may cause permanent consequences, and death remains possible.
