After a lot of lavish set-up and characters finally revealing who they truly are, The Lord of the Rings: The Rings of Power is ready to dive into the War Between the Elves and Sauron when it returns for its third season. We will also, at long last, get to see our pal the Dark Lord create the One Ring, setting up chaos for generations across Middle-earth.

At San Diego Comic-Con, The Rings of Power cast—with Benjamin Walker, aka High King Gil-galad, moderating—and crew took the Hall H stage to reveal more of what’s to come. Showrunners J.D. Payne and Patrick McKay shared a teaser and offered up more details on new characters arriving in season three. First, here’s that first-glimpse video: So, yes, a lot to unpack there, but that is definitely the One Ring. It’s really happening! Fans previously learned that Jamie Campbell Bower (Stranger Things) will play Celeborn, Galadriel’s long-absent husband, and Zubin Varla (Andor) is Khamûl the Easterling of Rhûn. But at SDCC, it was revealed that Eddie Marsan will play Thrain, the older brother of King Durin IV. Andrew Richardson is Anarion, the younger son of Elendil and Isildur’s brother. And Adam Young is Marnûkh, “a mysterious Orc who may not be what he seems,” according to a Prime Video press release.
