The Nine Knights

The City of Adema will bring great prosperity in trade to Camelot, but it's war-filled history has come back to haunt. Merlin wishes nothing more than to protect his friends, but how is he supposed to protect them from himself? There's something inside of him, and it's not his own.

Trigger warnings for suicidal/self-harming thoughts and gore. The story is pretty dark in content but still has some lighter moments, courtesy of Gwaine.
