Hi everyone, I am looking for a fanfiction that I read I think two years ago, I am trying to find it again but it seems disappeared, it's driving me crazy!
The plot I remember goes like this: starts with a scene of Arthur with another prince (I don't remember the name but he's probably an OC). Uther and the other king are friends, while Arthur is courteous with the other prince but doesn't have a good opinion of him. Then the foreign king dies and the other prince becomes king. The new king goes to a witch and asks for a spell that has an high price (the king newborn child) in order to have the whole of Camelot enchanted. Everyone in Camelot thinks that the new king is the real crown prince of Camelot, and that Arthur is the foreign king that took his place with a spell. It's clear in the story that it is not a body swap situation. Arthur is described as blond and blue eyed, while the "fake" Arthur is described as black haired, but everyone thinks that their prince is dark haired instead that blond. Merlin too is affected, in the beginning. Arthur gets apprehended and I think flogged, and thrown in the dungeon to await execution. I think that the spell becomes complete with the death of Arthur, but I am not sure. While Arthur is not having a good time in the dungeons, the fake crown prince acts differently from Arthur, leaving everyone, Merlin more than most, baffled. He also dismisses Merlin for another servant, that is the one who helped him with the spell. Merlin goes to see the "prisoner", and somehow believes Arthur. Merlin then helps Arthur escape the dungeons and they flee from Camelot.
Uther then decides to march with the army to the fake prince kingdom, to start a war. Arthur and Merlin go the same way, to stop him. I remember that during the journey to the other kingdom Arthur is very hurt, and Merlin very caring and protective.
When they arrive at the kingdom they infiltrate the Camelot camp and steal armour I think, then Arthur takes a horse and galops to Uther and the fake prince. Even the enemies soldier are also under the influence of the spell. Arthur challenges the fake prince in a duel to the death, instead of going to war. Here the fake prince shows his cowardice because at first he refuses, but under pressure of Uther I think he has to accept. Arthur defeats him easily, killing him and ending the curse.
Thanks to anyone who will be able to help!
