Merlin’s magic is bound and Magic reveal Fanfic

[lunader]

I’m looking for a specific fanfic that I can’t find or remember the name of, it’s one where Merlin, Arthur, and the Knights of the round table are captured by someone and Merlin is put in magic suppression/blocking shackles and is dying because of it and Percival breaks Merlin’s shackles and then Merlin helps them escape, and I might be confusing this part with another fanfic but I think it ends with Merlin tripping and falling on his face.

Other fanfics similar to this are welcome though.
