Amazon’s adaptation of The Wheel of Time series premieres this Friday, meaning fans can finally see some of their favorite characters come to life for the first time. Actors Rosamund Pike and Daniel Henney portray Moiraine and her Warder Lan–something that had been a dream for Henney–in the fantasy epic, who share a magical bond that grants them special abilities.

Speaking to the press about the upcoming show, Pike and Henney talked about their characters, and how they quickly bonded in real life because of a mishap with a sword while filming a pivotal scene.

“I use a real sword because the weight throws me off if I use a fake one,” Henney admitted. “I slashed her hand and we went to the emergency room because we thought her hand was broken and thought we had to shut down production and so that was how we bonded.”

Pike laughed off the incident and said in true Warder fashion, Henney was there at the hospital making sure she was okay. “I get to the hospital, and he’s waiting for me at the hospital,” said Pike. “True Warder right from the word go. We have a connection and you know, even when the shot is on me…and Daniel has a stunt double that rarely makes it on to set because he’s so good, and it’s not the same. It’s about energy and the feeling is different.”
