Prologue

What if Merlin had another secret? What if Merin's secret past comes back to haunt him? Merlin had a life as an assassin before coming to Camalot. And his past might just come to light, it might just come to kill the King. What will Merlin do? Will he be able to save Arthur in time or will the King's time finally come.

Hunith is dead so no moment of truth episode happened.
