While this event has not yet come to pass, it is inevitable. Will Aegardhros have a simple passing, or will his physical form be broken? Well, this small story will show us all who he is, or will become, at least.
It is the Fourth Age. A few decades in, really. Aegardhros has stayed in Imladris, after watching the town of Thônnadhor be emptied entirely. He goes to get a view of the west path, and what does he see? Bandits. Dozens of them. In his haste, he blocks off the entrance to the House which is no longer very Homely, and hides its few possessions very well. He then blocks off the entrance inside with whatever he can behind, before exiting through the balcony.
He then prepares to ride away, but sees the bandits had also been making haste, and they were entering Imladris. He takes out of blade, and he takes out his dagger. Their names no longer matter, for his home is nothing. He makes a quick prayer to the Valar, before riding out. He has had trouble getting in horses recently, and they have been worse than his steed of the Third Age. The war that ended it took the lives of most of I'Hosse, and has scarred Aegardhros since. He knows only that he will be reunited with them soon, and most of all, his parents, and his sister. He knows not of the fate of his brother, but he is sure he will find out making a stand to preserve this great land.
"Funny really," Aegardhros muttered. "I came in to this place as soon as I could, and said I would even be here alone to defend it against bandits, should the Halls here be empty... I never knew it would actually be like this," He ends his jest by having his steed go faster, and faster, which brought him face to face with the bandits. He charged in, relentlessly, cutting them down quickly in this last stand.
"Look out!" a familiar voice beckoned to Aegardhros. An arrow had soon come flying in to the left shoulder of Aegardhros, causing him to drop his dagger, and slip off of his steed. He would be on the cold hard ground, watching his brother, Lodhreth, cut down the rest, before collapsing in front of Aegardhros. "Wake up, brother, wake up! We need you, Aegardhros!" He would then sigh, and feel for a pulse, which would still exist. "Let's get you in to the Homely House, okay?" He would pick up Aegardhros, and the pair would go no Lodhreth's steed as they ride towards the Unhomely House.
Lodhreth would bash at the door, but would not prevail this time. He would give up getting in, and take him to a small area inside the Valley, where his mother's body was buried. "Look, Aeg, Mother's Garden. Remember this place? You promised to look after me, and now you leave me, the youngest of the Arodhel Three alone? When Aeluta went, I felt horrible... I can't let you go." Aegardhros would reach his hand out to grab Lodhreth's. "Tr-Trust me, brother... Thi- This is for the best. R-Ride for Valinor... I will see you.. Again, and always remem- remember... I... Love..." After a small amount of struggling, Aegardhros would give his last breath finishing off the sentence with "You.". Lodhreth would seen do a pyre upon his brother's body, knowing that there may be more bandits coming.
