Prime Video is gearing up to start production on Season 4 of 'The Rings of Power' in early 2027, following the premiere of Season 3 in November 2026. This new season is set to explore the critical events surrounding Sauron's corruption of Númenor, a pivotal moment in the Second Age of Middle-earth. Although Morgoth, the original Dark Lord, remains imprisoned and will not appear physically, his influence will be felt through Sauron's manipulations. Sauron will leverage Morgoth's legacy to sway the Númenóreans, convincing them that their god, Eru Ilúvatar, has denied them immortality. This leads to the establishment of a temple in Morgoth's honor, showcasing Sauron's cunning strategy to gain followers. Fans are particularly eager for potential flashbacks that could depict Morgoth's reign and his complex relationship with Sauron, providing a deeper understanding of their motivations. With the show's focus on psychological themes, Season 4 promises to expand on these characters' narratives significantly.
