So, we finally reach the end of my very first fanfiction, and in true Fire Emblem style, see the future of these characters. I wrote this story at least two years ago, and right now I think the ending is a pile of garbage. I was planning on writing a sequel...but that's it for now. Feel free to comment!
And so it was that Lord Matthew of Ostia was wed to the Fair Lady Josephine. Shortly after, Matthew was initiated Marquess Ostia, and although Hector was disgusted at first, he soon got over the past and formed a fast friendship with the new marquess. Jo was given the same privileges as Louise of Etruria as Lady of the court. Both being married to marquesses, the two of them meet regularly to discuss political matters, or just to chat.
X disappeared after the initiation ceremony, and no one knows where he went. There have been reported sightings of him around the continent, so it is assumed he has gone back to his travelling days, however he is actively pursued by mercenaries seeking out the famed assassin comrade to the demon who once massacred the Ostian nobility. It has been confirmed that he sends messages to his old friend every once in a while, but the marquess refuses to give out any information, saying that such communications are personal. Although there was a recent case where a certain mercenary with a grudge against Ostia, known only as 'Raven', attempted to sneak into the castle to pilfer the documents, but he was let off with a warning and a good kick in the leg.
After the ceremony Damien revealed his background story to his friends. We already know he was a half-demon, but it was divulged that he had actually, as a mortal half-demon, died at the age of eighteen. Death, feeling sorry for him, brought him back as a wraith to help eat souls (why Damien accepted this bizarre proposal is unknown).
Damien now continues his work as a soul eater and says he wouldn't spend his afterlife doing anything else – it's not like he has much to do anyway.
