*Sorry if it's a little unorganized, my thoughts while writing this was a little everywhere since I never made a good plan for the whole Rot thing... so hopefully this makes some sense lol I might fix it later if I feel like it

~What we know so far~

Chrysus District
Also known as the "Crisis District"

The lost district that was once known as one of the most prosperous districts has become under the corruptive forces of The Rot. A plague that devastates both humans and other living species, the land has become uninhabitable save for the few that were able to survive the plague, only to turn into the Sapíla: twisted, rotting living corpses, only some of which still retaining their ability to speak. Others have become incapable of human speech, instead communicating through snarls and shrieks. Despite their rotting limbs, they move incredibly fast, and while they don't seem to need to eat anything they attack any uncorrupted living beings that dare venture into the corrupted district, tearing and devouring their flesh. Those that were able to escape The Rot now live in the nation's capital district of Nicosia, ever fearful of The Rot potentially spreading to the rest of the continent. The Rot has been kept at bay due to the holy and divine priests from Salvia called The Salvus Order, making home bases around The Rot to prevent it from spreading to the rest of the districts. There is already signs of The Rot spreading into Laurus, Sabatos, and Porphura, though The Order has been working on trying to purify the land and even those that have become corrupted.

Classes of Sapíla
Sapíla is more so the blanket term for those that have been consumed and mutated by "The Rot," as there have been different classes of Sapíla documented by researchers and those that were trapped in the district when the barriers went up.

Scouts- the ones everyone knows of, the mutated remains of what were once people or animals that have now become rotting, skeletal creatures with the only things keeping them intact are the roots of the plant that brought about The Rot acting as their ligaments. Most only communicate through snarls and screeching and are exceptionally faster than a regular human. Due to how their extremities rot first, whatever is left of the bones in their hands have become razor sharp to help in tearing apart their prey. They travel in packs, wandering from one space to another. They do not hunt to feed themselves; instead they do so either to feed the other classes and to protect places where The Rot has spread. Scouts, as far as we currently know, do not eat and are instead essentially puppets for The Rot to use as the first line of defense against those that would threaten the rest of The Rot.

Screechers- mutated remains of people that have mutated almost into twisted tree-like forms that are typically sedentary and survive on "food," which are animals or humans that haven't been infected or are in the early stages where they have not fully been mutated. If any living thing comes within a 3 foot radius of these creatures, they let out a debilitating screech to alert Scouts to their location in the hope that the Scouts kill the intruders. After the Scouts have taken care of the unfortunate prey, that is when the Screecher starts feasting on the remains that may or may not still be alive. When eating, root-like filaments spilt off the "legs" of the Screechers before hooking into their injured prey, draining the bodies of blood and other needed nutrients. Once they've finished getting what they need from the bodies, the filaments then harden to disturb and soften up the soil beneath them before pushing/pulling the remains down into the ground so new prey doesn't realize what had happened prior, the whole process roughly taking a day. Unlike Scouts, Screechers are solitary creatures and stay away from each other so they don't have to compete for food. They become dormant and even slowly die if they haven't fed in a month or so but can become reanimated if a severely injured prey is within their vicinity.

Pollinators- slow moving mutations that spew out large amounts of "pollen," these strangely beautiful mutations were once people with high levels of magical energy. The mutations appear as though the hosts' bodies had become purely made of or covered in flowers. The pollen they expel causes people to slowly fall asleep, as when people are asleep, they're more likely to breathe deeply and therefore likely to breath in more of the pollen for The Rot to take root in their lungs. In the rare event that Scouts cannot kill prey, they will start to shepherd them towards the nearest Pollinator, keeping them a certain distance away from it where they will be in the pollination zone but far enough to not find the Pollinator.

Infection
The Rot is a purely airborne disease, spread about with the pollen of the flowering invasive species known as the Athira Loosestrife. While it looks like a flower, it in fact behaves more like a sort of fungi, with its pollen acting as spores that are released when the plant reaches maturity. Infection only occurs when the subject's lungs are exposed to large quantities of the pollen-like spores and remains untreated. The spores will then begin to give birth to bacteria that in turn mutates the host's system once the optimum conditions are reached.

Transmission
The only ways that The Rot spreads is either from the Athira plants themselves or from those infected and behaves similarly to airborne diseases. Airborne diseases are caused by bacteria or viruses that are most commonly transmitted through small respiratory droplets. These droplets are expelled when someone with the airborne disease sneezes, coughs, laughs, or otherwise exhales in some way. These infectious vehicles can travel along air currents, linger in the air, or cling to surfaces, where they are eventually inhaled by someone else. Airborne transmission has varying capabilities. Airborne diseases can travel distances greater than 6 feet and remain infectious in the air from minutes to hours. This largely depends on the type of ventilation and preventative measures inside the building. 

Symptoms
Before the host is fully mutated, there are signs of infection that ranges based on the stage of infection. Chances of surviving the infection is only possible in the early stages.

Symptoms shown within 1-2 weeks after infection:

•Fever

•Cough

•Runny nose

•Red and watery eyes

•Increased libido/Need To Be Around People

Symptoms within 3-5 weeks:

•Coughing worsens; patient starts coughing up large amounts of phlegm and blood

•Chest pain

•Fatigue

•Weight loss

•Loss of appetite

•Chills

•Fever

•Night sweats

•Nightmares/Strange & Unusual Dreams that leave the patient feeling disoriented upon waking up

•Strange markings start appearing on the patient's skin as well as their veins start appearing darker while the skin becomes almost transparent

The more severe symptoms include:

•Ear infections

•Diarrhea

•Pneumonia

•Encephalitis (brain swelling)

•Desperation to be outside and be near the Athira Loosestrife plant as it's scent is the only thing that brings comfort to the patient

*Once the severe symptoms appear, especially during the fifth week, there's little to no hope of turning back and treating the infection unless a large amount of holy/purification magic is used to reverse the infection

Symptoms in Weeks 6-8
•Patient falls into a coma where their body begins to undergo the mutation process. Their vital signs remain normal even while the insides of their bodies began to rot, the bacteria born from spores of the loosestrife beginning to eat through and merge with the patient's system, eventually finding their way into the bloodstream and spreading through more of the patient's body
•Within a night after "coding," the patient would become fully mutated into a moving corpse, its movements erratic and jolting while strangled shrieks and cries escape their lips before going out and attacking non-infected people and animals.

Origins/Story
•No one is sure where The Rot came from or how it appeared on the coasts of Chrysus, but it first started appearing near the coast, thriving around the more humid and warm environments in the form of a pretty little flower with a mix of soft and vibrant pinks, purples and white petals.
•People were drawn to the strange new flower due to it's soothing and nostalgic scent, sometimes described as a mix between a sweet floral scent and almonds or vanilla with a strange but pleasant sourness towards the end of it.
•Due to its beautiful colors, scent, and how it started popping up everywhere, people began selling them in flower shops in arrangements, taking the place of things like Baby's Breath. One of the first shops that started doing this was Athira's Flowers & Candles, a shop that sold flowers and made their own homeopathic goods like candles, soaps, lotions, oils, etc. using local plants and flowers. They would end up naming the new flower Athira Loosestrife, both after their shop and because the name represented how the scent of the flowers made you "loose strife," calming any who smell the flowering plant.
•It would end up dying once winter hit, but it would come right back as soon as spring came around, growing even faster than it had when it first appeared. It would take a couple years for the plant to start becoming a real hassle.
•During the height of the flowers' maturing, people that lived near the plants started exhibiting allergic/flu-like symptoms. It wasn't treated as anything strange at first, it was only when their symptoms started worsening that people started thinking something was going on as local hospitals and inns were being used to hold those that were suffering as the number of people affected grew steadily.
•The Athira Loosestrife continued to grow faster than it had the previous years, starting to out-compete local plants as it spread over the ground like an infection, the roots of the plants tangling around and infecting other plants, crossbreeding with other flowers and starting to grow on the trunks of trees.
•The initial outbreak would quickly be followed by the patient's loved ones becoming sick and compromised as well by the time that the first mutations (Sapíla) would emerge, attacking all non-infected humans and animals.
•It would eventually click for scientists and doctors sent to figure out what was happening that the disease was being caused by the Athira Loosestrife. They would try to burn the flowers or use various herbicides, but nothing really ended up working, almost as if there was a more... mystical reason why they weren't dying. And so, they brought in priests from the Salvia District to see if holy magic had any chance of destroying the flowers. There would be some success with the containment and withering the flowers, but it wouldn't destroy the flowers completely.
•Most of the spreading of the flowers remained at the coasts, the flowers thriving most in the humidity near the ocean but also where larger fields of other plant life were located. As the grain capital of Katharos, there would be many grain and wheat fields that would become overrun and choked out by the Loosestrife.
•Evacuation efforts would soon take place, however it didn't become mandatory until the Sapíla, namely the Scouts, started appearing and hunting down non-infected people... while also seemingly nudging them toward fields of the Athira Loosestrife. It would only get the moniker "The Rot" once people realized that the flowers were making everything else it grew on/near start to rot, accelerating the "circle of life" to make it become compost and foster more growth for the loosestrife.
•Scouts were next to impossible to actually kill, with only dismemberment being a surefire way to take them down... until the roots of the loosestrife inhabiting the bodies re-grew, reassembling the bodies and pulling them back together
•It was eventually decided to quarantine the entire district as more and more Scouts began appearing and The Rot continued to spread while the Salvus Order, a group of men and women made up of scientists and those capable of holy & purifying magic. They've kept much of The Rot contained, but have yet to make any headway on how to destroy The Rot in the past 27 years its been taking over the Chrysus District, only that dark magic seems to be helping the flowers thrive and making them impervious to normal means of destruction
