One such person of interest was a mysterious white-haired character who appeared in one of the show’s final trailers, a character who was misidentified as Sauron played by Pistol actor Anson Boon.

But the show’s fifth episode revealed the truth behind the white-cloaked character, and the people that they were traveling with. Here is everything you need to know.

‘Rings of Power’: Identity of The White Cloaks Characters Finally Revealed

The fifth episode, titled “Partings,” sees the white cloaks characters finally reveal themselves, as they are shown briefly at the site where The Stranger (Daniel Weyman) crash-landed in Middle-earth.

In the credits for the episode the trio are named The Dweller, The Ascetic and The Nomad, and it is The Dweller who was misidentified as Sauron played by Boon.

The Dweller is seen heading to the crater where meteor man The Stranger landed in Rhovanion, and the character looks back up at their two companions.

Bridie Sisson portrays The Dweller, while Kali Kopae takes on the role of The Ascetic and Edith Poor plays The Nomad, according to the credits.

When initial rumors began circulating about The Dweller being Sauron, executive producer Lindsey Weber told TIME: “We are enjoying all the speculation online and can tell you Bridie Sisson is an incredible actor.

“We also thought fans might like to know that her character is traveling from far to the east—from the lands of Rhûn.”

This is an important hint as to what The Dweller, Ascetic and Nomad are doing because the Rhûn, according to J. R. R. Tolkien’s lore, is where the Easterlings dwell, a community who were loyal to Sauron.

The Easterlings are said to be united in their hatred for the West, and they were followers of both the Dark Lord and his predecessor Morgoth, fighting alongside them during the Second Age of Middle-earth and beyond.

With this in mind, it seems likely that The Dweller, Ascetic and Nomad have set out across the planes of Middle-earth in search of Sauron, who during the Second Age went into hiding and assumed a false identity following Morgoth’s defeat.

Whether this means The Stranger is Sauron is unclear, though the character seems more likely to be a different character of importance from Tolkien’s novels.
