Syfy has picked up the fourth season of Merlin in the US.
The cabler, which has already aired the first three seasons, confirmed to TV Guide that the British series will return to the network.
Merlin, which stars Colin Morgan, Bradley James and Katie McGrath, picked up a series high of 1.87m for its season three finale on Syfy earlier this year.
The fourth season will focus on Merlin as he tries to ensure that Arthur "fulfils his destiny as the Once and Future King".
Merlin's executive producer Johnny Capps recently claimed that the fourth season goes to "interesting and dark places", while his colleague Julian Murphy has revealed that talks about a fifth season are already under way.
The fourth season of Merlin is expected to air on Syfy next year.
