Everyone must go watch this Merlin vid,
Unsteady Ground, right now. Morgana can see the shape of things to come. The song, the use of clips, the story it tells of the cracks already starting to form around them are all breathtaking.
(And it's the perfect companion to the beautifully tragic Arthur vid
Red.)
Merlin keeps on attracting these amazing vidders, who can spin the series' straw into gold. This, peoples, is what fandom is for.
