Cursed Wells
**Openings that lead to the Cursed Reserve, a subterranean ecosystem of countless curses and that spans the entire planet.** They are usually the result of disturbances, imbalances, and/or blockages of vast reservoir of cursed energy that flows beneath.
Curse spirits that emerge tend to be unnaturally powerful due to the optimal environment they crawled from as well as generations of vying for survival against other equally dangerous cursed spirits.
A particularly nasty formation of a cursed well may erupt and flow the subterranean energy to the surface. These eruptions eject dense amounts of cursed energy that appear as *fog or mist that is visible to even non-sorcerers* and result in the mass spawning, outbreaks or surges of cursed spirits. Non-sorcerers inside exhibit adverse mental health and tire more easily due to their inability to combat the diffusion of their cursed energy.
The source or theoretical wellspring of this cursed energy is unknown; though it is certainly not humanity.
Cursed Spirits formed of it are incapable of human language without prolonged exposure to surface-side cursed energy, which includes:
* Being outside mist * Combat against a sorcerer * Feasting on surface humans/spirits
Those capable of speech will initially do so in unknown tongue.
**Though their alignment is often neutral, they are no less dangerous than surface spirits.** They are more often than not more dangerous; being driven by a general instinct to survive, feast, and/or destroy rather than any specific hatred toward humanity.
*Their constitution is more compressed, stable, and refined than normal cursed spirits. The strongest among them even display a heightened resistance to RCT and even a limited ability to produce RCT.* Albeit the caveat of doing so is the risk of permanent deformation of the soul or an chain reaction that will quickly render them dust.
Cursed spirits formed of this energy can be starved. Their greater power and fortitude comes at the cost of requiring more than negligible but not too terrible intake of cursed energy as sustainance *(they can survive starvation much longer than a human if needed).*
Outside of their natural environment, this requirement sharply increases due to the sparsity and diffusion of their foreign cursed energy.
