The clockroom

When Arthur finds the clocks in the dungeons, he does not think they would change his life forever.
Suddenly he finds himself in the future, living lifetime after Lifetime with Merlin, long after his own death. And after each visit, he finds himself back in Camelot in that clockroom, where it all began.
 Arthur isn't sure how it works. Maybe it was just a strange dream.
 But with time he comes to love these new worlds.
And Merlin.
 Until he realizes they were never dreams at all. And he truly was the once and future king.

Alternatively:
A retelling of BBC Merlin from Arthur's point of view. How he falls in love with Merlin and Gwen at the same time and how that influences his actions throughout the series.

Edit: While I hated the way this was executed the first time around, I still love the overall concept of the story. And I am afraid that I'm insane enough to try working on it again.
This work involves a lot of research and I'll just go along with the episodes as I see fit. I won't be able to make this whole thing perfectly coherent. It's just too much work. But I will do my best.
