The fifth season will indeed venture into Camelot as OUAT producers are currently casting

for three key characters: Merlin, King Arthur and Guinevere. It is currently unknown if Lancelot will appear in flashbacks, modern day scenes or both, and the same goes for Merlin, King Arthur and Guinevere.

As the TVLine report describes, Merlin is "a man with great wisdom and intelligence beyond his years," who is invested in the idea of duty.

For Arthur, OUAT producers are looking for another British actor in his 30s or 40s. In OUAT, Arthur is "good and just ruler" though he is "a master manipulator who can carry a grudge to the grave, and maybe beyond." Arthur will have an "eternal burning love" for Guinevere.

As for Guinevere, producers are hoping for a Latina actress in her 20s or 30s. Guinevere is a "headstrong queen" who happened to fall in love with Lancelot.

Once Upon a Time season 5 premieres Sunday, Sept. 27 at 8 p.m. ET/PT on ABC.
