General
Frequenting the side of Silva Forest closest to the Alasre Mountains, fell perytons are considerably more disquieting than their mountain counterparts. With their skull faces, imposing height, tattered wings, and striking colors, they are majestic and terrifying to behold, and their powers over decay and destruction mean they are treated as ominous portents, best avoided. However, while regal from the healthy distance that most non-magic users like to keep, magi who keep fell perytons report that up close, they can be adorably clumsy and silly - sometimes getting spooked by their own wings, attempting to flee, and crashing straight into whatever is nearby, be that a tree, a fence, or another fell peryton. After recovering, the fell peryton almost resembles a cat in how it proceeds in utter dignity, as if nothing has happened.
Egg
Being close to this egg makes you feel slightly uneasy, and holding it makes you faintly nauseated.
Hatchling
Fell peryton hatchlings are surprisingly active and dextrous immediately after hatchling, and love nothing more than to prance through their territory, exploring every corner. They do not have the raw power that their adult counterparts do, which is fortunate, as they also have no control over when and where their magic spills, spreading rot and fungal infestations wherever they go. In Silva forest, most healthy plants and creatures are more than capable of fending off the weak rot spread by a young corrupt peryton, but old and weak plants get cleared out and broken down into rich compost, clearing the way for a new generation to spring in their place. Magi raising corrupt peryton hatchlings are strictly banned from bringing them anywhere near the Keep, though, lest they accidentally rot away critical supports or worsen the ailments of patients traveling to the Keep for magical care.
Adult
Despite their fearsome powers, fell peryton are shy creatures, rarely leaving Silva forest unless called upon by their magi. Adult corrupt perytons no longer randomly spill their destructive magics, and apply their rot with deliberate intent to old, large trees that are past their prime, feeding on the fungi their powers spawn. As the tree decays and topples, new growth spurred by light shining through the freshly cleared canopy and the rich compost left behind can take its place.
