The Hollowing - MLP Infection AU

A mysterious fungal sickness spreads across Equestria, leaving infected ponies hollowed and broken versions of themselves.

Twilight is convinced it all began with Sweetie Belle and races desperately to find a cure. But Starlight sees things differently-how could a young foal, the supposed source, survive far longer than healthy adults struck down around her?

As the Cutie Mark Crusaders wrestle with their own fractured bonds, the Mane Six grapple with hidden fears and secrets, while Celestia and Luna confront growing unrest within their realm.

In a world unraveling, alliances will be tested, truths questioned, and hope stretched thin. What comes next could change Equestria forever.
