A black knight crashes Arthur's coming-of-age ceremony, throwing down the gauntlet to any knight who will fight him, killing all who do, one day at a time. Gaius discovers he is Uther's dead brother-in-law, now a wraith summoned from the grave by the witch Nimueh, seeking revenge for the death of his sister who died giving birth to Arthur. His intent: to eventually fight and kill Uther. Merlin learns that only a special sword burnished with a dragon's fiery breath can kill the knight. To that end, he asks Gwen for the best sword her father ever forged (the sword later known as Excalibur) and asks the imprisoned dragon to burnish it. The Dragon, however, tells Merlin that, once created, only Arthur should wield it, as evil will come of it otherwise. Merlin gives his word. Unfortunately, Uther has Arthur drugged and locked in his room, preparing to face the wraith himself. With Excalibur in his hand, victory might come but would leave Uther in control of a powerful magical weapon.

The sword that kills Tristan du Bois is meant to be Excalibur, yet the sword is never actually mentioned by its real name during the entire TV series. See more
When Merlin tries to burn the Black Knight with magic, the knight is standing on packed ground with many footprints and there is a cobbled road nearby. The knight doesn't move at all, but when Merlin and Arthur, and later Uther look at him through the windows, he is standing on a smooth grass field with no cobbles or footprints visible. See more
