A Lantern in the Dark (слэш)

After living in Camelot for ten years, Merlin has accomplished nothing - magic is still illegal, Albion remains a mirage, and he's still 'just a servant' who is lonely and tired of his hopeless pining for Arthur.
Merlin will pay a heavy price for his lack of direction as Arthur’s walls of denial crumble and Morgana’s plans to destroy Emrys approach fruition. In his desperation to save the Golden Age of his dreams, Merlin will have to call upon his magic like never before, testing the old adage that power corrupts - and absolute power corrupts absolutely.
