One-Shot book, although it probably won't just be one-shots, if you have any requests or ideas please let me know. Disclaimer: I don't own Merlin, BBC does. I would have thought this obvious but...

After Arthur's death, Merlin is caught alone with out him for centuries. He has lost count of how long it's been. After all, Merlin is nothing without magic, but turns out he is nothing without Arthur. Kilgharrah said Arthur will rise again once Albions need is greatest, but what if it's when merlins need is greatest?
