The series finale of BBC's Merlin was left speculatively open ended. In the concluding scene, an obviously aged Merlin is depicted wandering just beyond the outskirts of Avalon from whence Arthur restfully awaits to return. The viewer then sees a truck speeding down the road. Though one of Arthur's titles is the Once and Future King, apart from C.S. Lewis' "That Hideous Strength" where Merlin returns and DC Comics' "Camelot 3000", there do not seem to be that many authors that explore that particular aspect of these tales and legends.
