Disclaimer: I do not own Merlin, this is an alternate universe fan fiction, in which I have used the characters, places and the story from the BBC TV show which I do not own.
No one knew who he was; what he looked like, where he lived.
What his name was.
But he was always there: no matter what the time of light or dark, no matter what the place, he was always there.
A protector, guardian.
