Assuming that it was Merlin that tethered the darkness. I know that is what they have said up to now, but there is plenty of time for that story to twist up unexpectedly.

If they get to the "Lady of the Lake" (#NoSpoilers, please), which seems likely since they have Merlin trapped inside a tree, there are parts of the story that could indicate that she is also quite powerful. I'll be interested to see how they continue with the story. (And FYI, in the Arthurian Legends, in case you weren't aware, it was one of the Ladies of the Lake that was responsible for trapping Merlin in a tree.)
