A new red star appears in the sky. It streaks across with unnatural swiftness. With it comes a new threat, raining down from the day sky in great strands of death that eats all organic matter it can find, leaving the terrain scarred and ponies dead.
Based on Anne McCaffrey's Dragonriders of Pern, but set in Equestria. We will not be using Pern characters, nor is it required you read any Pern books, or even know what Pern is, in the end. This is a story set in Equestria, with the ponies having to deal with a new natural threat/calamity and hopefully rising to the occasion.
