“A part of this legend has always been the sword stuck in the stone,” says Zetna Fuentes, who directed the first two episodes of the series. “This was a moment where we felt we could play on that … It was fun to find those nods to the legend that we could also turn and do it in a different way.”

Stories about King Arthur have been told and retold for centuries. Wheeler and Miller’s shared affinity for these legends, and their hopes of bringing something new to the lore, led them to focus their story on Nimue – one of the names associated with the Lady of the Lake.

“Nimue is the key to it all,” Miller says. “She’s the thread [through] which we’re exposed to everything about the mythos that we associate with Camelot and Arthur and all the other aspects.”

Wheeler explains that the existing imagery and mystery around the Lady of the Lake character captivated them. “That image of this woman’s arm reaching out of the water and offering the sword to Arthur, it evokes all of these interesting questions.

“Who was she? What is her relationship to Arthur? Why does she have the sword? And as we began to work backwards from there this idea that a woman held the Sword of Power before Arthur felt like a story worth telling,” Wheeler says.

In Cursed, Nimue is a Fey teenager with powerful, and sometimes uncontrollable, magic. Because of her powers, she grows up an outcast in her village. After a religious order of intolerant zealots massacres her people, she sets off on a journey to deliver the Sword of Power to Merlin, per her mother’s dying wish.

Over the course of the first season, Nimue stands up against the warring human factions to help save the remaining Fey.

According to scholars, there are numerous iterations of the Lady of the Lake, whose earliest appearance can be traced to French literature of the 12th and 13th centuries. Some authors have portrayed her as good, while others have portrayed her as evil.

Besides the stories about how she gave Arthur the sword Excalibur, different versions of the character are known for raising Sir Lancelot, who became one of the most famous Knights of the Round Table; enchanting and imprisoning Merlin the magician; and accompanying Arthur to Avalon.

In some stories, she even replaces Merlin as King Arthur’s adviser.

In approaching the show, Fuentes explains that they were aware of the literature and various film and TV adaptations around Arthurian legends, but they didn’t feel beholden to any previous interpretations of the characters or their stories.

In addition to Nimue, Cursed is peppered with familiar characters from the lore, including Arthur, Merlin and Gawain. The show’s iteration of Arthur is a young mercenary who hungers to be more than a man burdened by his father’s debts, while Merlin is a drunk who can no longer use magic. Gawain, also known as the Green Knight, grew up in the same Fey village as Nimue.

“Seeing it through Nimue’s eyes as a character who we know exists, in our minds, sort of before the traditional story begins gave us some latitude,” says Wheeler. “It gave us an opportunity to introduce these characters in different ways.”

Scholars are divided on whether King Arthur, the legendary literary figure, was also actually a historical figure. Geoffrey of Monmouth is credited with popularising the legend of King Arthur through his 12th-century book, The History of the Kings of Britain.

Some historians believe Arthur could have been based on an actual warrior from the fifth or sixth century, while others believe he’s a composite of various figures, and still others believe Arthurian legends are not based on anybody real.

Core elements of Arthur’s story, from various sources, that have been remembered the most over the years include how he pulled a sword from a stone (or anvil) to prove the legitimacy of his claim to the throne; his Knights of the Round Table and their quest for the Holy Grail; his tutelage by Merlin; and his marriage to Guinevere.

In the legends, Arthur is generally understood to be the son of King Uther Pendragon and Igraine – a backstory that differs from the character in Cursed.

Over the course of the show’s first 10 episodes, characters who were initially introduced under one name are eventually revealed to be characters with much more significant ties to the Arthurian legend.

Wheeler relishes the freedom to reinterpret these characters – Gawain, Perceval and Guinevere among them – but says the goal is to take them to a more recognisable place.

“Something Frank was very insistent upon, and rightfully so, is that we can change them, we can push them, we can stretch them, [as long as we] remain true to them,” says Wheeler. “And make sure we know our map back to who these characters are.”

“Even if we aren’t telling you who these characters are, in some ways, their destiny’s already set,” says Miller. “We know what we’re aiming toward.”
