This is a "reprint" of one of my fanfiction stories from Fanfiction.net from 2011.
An event is happening in Ponyville that may well change things forever. Something heralded by an out of control storm one night. By the arrival of a powerful rainbow.
Mysterious mythical horses called the Sleipnir have come to Ponyville on a mission to gather intelligence about ponies. Two half sisters. Descendants of Thor and Loki. What is their intentions for the ponies and what will come of their interactions? What will the "final judgement" of Equestria be?
And who are these distant cousins who just happen to show up at Sweet Apple Acres looking for a place to stay while they visit Ponyville? Two Earth pony mares that Applejack had never met before.
