Once every five hundred years in Equestria an event occurs. It is no festival or holiday, it is the blood moon. The first recorded incident of the blood moon was three months after Luna was banished. During the first blood moon there was widespread panic throughout all of Equus. Monsters from all over the world ventured from their homes and wrecked havoc upon all nations. Many were killed during this time. Most were military personnel that fought to protect their homeland from the monsters that threatened them. The terror every nation felt died when the golden sun broke the horizon ending all of the monsters rampage.
