Mormo's Corruption

The Corruption is a supernatural force which causes mysterious afflictions. It is associated with trips inside the Scar, it's artifacts, the Great Cataclysm and other creations of the Witch Tyrant.

Laymen also use this term for all afflictions gained while travelling inside the Scar, including curses and blessings of known origin, infections, normal injuries and so on.

There is no known cure against Corruption.

Causes

 * being inside the Scar (it's stronger in certain areas and becomes more severe closer to the center)
 * being exposed to an Echo of the Cataclysm
 * being exposed to the corrupted storms that originate from the Scar during an Echo of the Cataclysm
 * being exposed to certain creatures, anomalies or artifacts from the Scar
 * practicing certain magic

On creatures

 * When a creature gets injured or stressed out while being affected by Corruption, their body and mind might heal back in a different way as they have been before. This can range from sudden mutations to insanity.
 * Dead creatures exposed to it are likely to return as Undead.
 * Corruption can be inheritable. Children of parents that have been exposed to large amounts of it might be born as monsters or develop concerning traits later in life.
 * It can cause nightmares. This may lead to the dreamer sleepwalking, cause them psychic harm, exhaust them etc.
 * A symptom called the Whisper may manifest, corrupting even the soul.

Others

 * Wild magic surges may be triggered and magic can become unstable.
 * Reality can become distorted and natural laws work differently.
 * The boarders of the world are weaker and it's easier to cross planes. Also planer rifts may occur.
