At this year’s San Diego Comic-Con, the creative team behind Amazon’s Lord of the Rings series teased even more surprising turns for its mysterious man from the stars.

The first season of Amazon’s The Lord of the Rings: The Rings of Power took its sweet time revealing the true identities of its two most mysterious characters. But when the show returns next month, it seems like it’s going to hit the ground running with big reveals about how Sauron and the Stranger will change Middle-earth. A new, lengthy trailer revealed at Comic-Con gives a good sense at what fans can expect in season 2.

According to Amazon, the new season will be focused on Sauron’s return. “Cast out by Galadriel, without an army or ally, the rising Dark Lord must now rely on his own cunning to rebuild his strength and oversee the creation of the Rings of Power, which will allow him to bind all the peoples of Middle-earth to his sinister will,” the streamer explains. It looks like this season will also be a good one for fans of fantasy monsters: the likes of the giant spider Shelob, shape-shifting Barrow-wights, and a Sea Worm will make an appearance.

Season 2 of The Lord of the Rings: The Rings of Power hits Amazon Prime Video on August 29th.
