"Idaludusa has been a problematic area of the Underbelly for many years. Not only to several severe diseases hail from there, but when the natural inhabitants, the Mycanids, begin to wander outward on breeding exbitions, they can leave patches of this disease within various locations." — Doctors within Gloomdeep
Lungrot is a progressive disease, unique to Mortalis, and is usually contracted at a young age and worsens over time. However, an individual can be a carrier of the disease, which can pass genetically onto their children interestingly enough. It is thought that the spores within the enviroment, typically recognized and localized within South East Idaludusa, from the Mycca variety of Mycanids which can be identified by having red tops with white protruding specks.
The Spores are tradtionally supposed to be sensory beacons for other Mycca Mycanids to locate others of their kind in the area, a sort of pheromone. It has a sweet smell even to Mortalis, which causes many young children to delightfully pick up spore colored flowers covered in the spores to keep.
Infection is almost instant upon smelling, which makes the disease so deadly. The spores take root within the humid and dark area within the lungs. There is a 'fluent infection period' where the spores can be coughed and sneezed out progressively, which can cause this to spread to others. However, specially produced cures allow the spreadability of the disease to be suppressed. Outbreaks of the disease are common within lower income areas within the Underbelly of the World.
Because of the fact that this disease is progressive and its own existing fungal infection, this can not be cured by magical means. Doctors have been working hard to find ways to completely cure lung rot, and have made great strides with the medicine called 'Antiforris', however this specific cure needs to be generally shipped fom Zauleha's institutes, which by the time it reaches The Deadlands or Obairix where other major population centers of Mortalis are, the prices skyrocket because of expiration times.
