Summary: Arthur does not take it well when he discovers Merlin's magic. Future fic. Dark!Arthur.
Notes: This fic is sort of schizo, as it totally didn't want to end where I meant it to, and the portions beyond where I meant to end are just - very much not what I intended. Sorry? Also, apologies for any technical mistakes, as I didn't read through very carefully once I finished writing, because I just wanted to get rid of the damn thing.
WARNING! Contains torture and non-consensual sexual situations. If this offends or squicks you, DO NOT READ
