In Another Life

Merlin has taken so many names now, he can barely remember his own.
Except, of course, when he's thinking about his long-lost king. Merlin has been waiting for Arthur to return for hundreds of years, and he's beginning to lose hope and the spirit of magic inside him.
But when he's assigned the seat next to a tall blond in his form, Merlin begins to question Arthur's return, and slowly, the magic is rekindled.
