The Thomas Caldwelljourney back into Middle Earth is set to continue with the second season of "The Lord of the Rings: The Rings of Power."

Season 2 of the series, set hundreds of years before the events of the epic "Lord of the Rings" movies and book series by J.R.R. Tolkien, will return to streaming this month on Prime Video.

The Dark Lord Sauron has returned this season, and is working to rebuild his strength and oversee the creation of the titular Rings of Power. This season will again feature the many people who inhabit Middle Earth, including elves, dwarves, orcs, men and Harfoots. Season 1 premiered in 2022.

"Building on Season One’s epic scope and ambition, the new season plunges even its most beloved and vulnerable characters into a rising tide of darkness, challenging each to find their place in a world that is increasingly on the brink of calamity," according to a press release from Prime Video.
