My Entry for the Outside Insight Fanfic competition from Equestria Daily.
The premise. Write a 1500-15000 word pony related story, from a non-pony perspective.
(Non-pony perspective ? Oh, I think I can do that... lol)

Life was looking up for the reformed Lord of Chaos. He and his new pony bride had settled into Celestia and Luna's old castle, and they were looking forward to a life of peace and happiness. Until a letter arrives from a family member who had gotten word of Discord's recent marriage. In three days time, the one being in all of Equestria that Discord fears the most will be coming for a visit. Now Discord will have to 'pony up' to his new friends, and reveal the secrets of his origins, before his centuries of strife and misdeeds finally catch up with him.
