The Horror From Beyond The Gate (Fullmetal Alchemist: Brotherhood fan fic)

It has been eight years since we left our heroes. Ed is married to Winry and is on a break from his alchemiy research in the East and Al is back from the west. Roy and Riza, now married, live in central as as Roy rules the nation of Amestris as their Fürher. Ling is now Emperor of Xing with Lan Fan as his main guard. How will their sound lives change as loved ones who were supposedly dead start to turn up alive. Then to add to the confusion the seven homunculi are somehow back with a claim of being on their side. The homunculi come with word from truth that a monster once locked away has escaped and is now endangering Xing. (I do not own fmab or the cover art! Only a few original characters and the plot)
