The search for the missing Holy Grail officially starts in the next episode of “Knightfall.”

According to the synopsis for Season 1, episode 3 of the History series, Landry (Tom Cullen) and Tancrede (Simon Merrells) travel to investigate the Grail’s whereabouts following an order given to them by Pope Boniface (Jim Carter).

But the Templars aren’t the only ones who are looking for the Grail. After De Nogaret (Julian Ovenden) learned from Gawain (Pádraic Delaney) last episode that the Pope went all the way to Paris to discuss matters about the long-lost Grail, King Philip’s (Ed Stoppard) right-hand man also tasks his minions to find the Grail before the Templars do.“We must recover the Grail first for ourselves,” De Nogaret says in a trailer teasing the rest of the show’s freshman run.

Meanwhile, in the trailer for episode 3, De Nogaret appears to instruct one of his underlings to steal a scroll from the Templars. While the content of the scroll is unclear, it’s possible that it contains details about the location of the Grail. Also in the clip, a man tells the Templars that the Grail will “destroy” them all.

In a featurette released by History earlier this week, Ovenden explains why it’s important for De Nogaret to get hold of the Grail before anyone else. “He realizes that the Grail itself is a very very powerful symbol,” the English actor says of his character. “It’s a symbol by which the Catholic Church can control people. The idea of the Grail reinforces the idea of Christ, that Christ is existent — something that De Nogaret doesn’t believe and something that dilutes the power of the French government.”

Elsewhere in the upcoming episode, the plotting behind the royal wedding becomes deadly. Last episode, Pope Boniface decided that Princess Isabella of France (Sabrina Bartlett) would marry Prince Lluis of Catalonia. But because De Nogaret strongly believes that it would be better for France if Princess Isabella will tie the knot with Prince Edward of England, it is expected that De Nogaret would do anything to thwart the nuptial between Princess Isabella and Prince Lluis.

“Knightfall” Season 1, episode 3, titled “The Black Wolf and The White Wolf,” airs on Wednesday, Dec. 20 at 10 p.m. EST on History.
