The Everfree Infection is an infection that infects ponies and creatures transform them into horrifying, tree-like beings through a fungal or spore-based disease. Origin and Spread Patient Zero: The outbreak often traces back to the Everfree Forest, originating from an unusual bug or plant disease. Transmission: It spreads through spores, environmental contact, or bites from the already infected, turning Equestria into a grim, panic-stricken wasteland. Stages of Infection The disease typically progresses through severe physical and mental deterioration: Stage One: Lethargy, loss of appetite, and infection spreading across or under the coat. Isolation or burning is often deemed the only recourse as treatment fails. Stage Two: Wooden branches sprout from the spine and body, extreme weight loss occurs regardless of food intake, and mental health severely deteriorates into violent hostility. Stage Three: Branches release new spores, bones elongate, extreme thirst sets in while the body rejects liquids, and the afflicted actively stalk and attack survivors. Princess Celestia and Princess Luna are not infected. Canterlot is a safe zone. The Crystal Empire is ruled by Princess Cadance and her husband Shining Armor. The Crystal Empire is a safe zone. There's a new kingdom called the Night Orchid Kingdom that is the kingdom of the Bat Ponies.
