5 Essential Rings of Power Episodes to Rewatch Before Season 3

The Lord of the Rings: The Rings of Power returns for its biggest season yet on 11 November 2026, and the stakes have never been higher. Sauron stands on the edge of forging the One Ring, the Elves have suffered their first great defeat, and Middle-earth is about to enter its darkest chapter. Season 3 opens after a five-year time jump.

A full rewatch means 16 episodes of an hour or more, but you do not need all of them. Five carry almost everything Season 3 needs: the forging of the rings, the reveal of Sauron, the birth of Mordor, the fall of Eregion, and the founding of Rivendell.

1. Season 1, Episode 1 — “A Shadow of the Past” (1 September 2022)

Every great story starts with a wound that never healed, and “A Shadow of the Past” opens with the deepest wound in Middle-earth’s history. The prologue takes us back to Valinor and the War of Wrath, where the Elves fought Morgoth, the first Dark Lord and the master Sauron once served. Galadriel loses her brother Finrod in that war, and her oath to hunt the evil that killed him drives the entire series.

Why it is essential: This episode lays down the show’s central idea — evil never truly dies, it only hides and waits. Every Season 3 storyline grows from seeds planted here: the Elves’ fading light, the Dwarves’ hunger for mithril, the Harfoots’ wandering, and the shadow over the Southlands.

What to watch for: The friendship between Elrond and Durin IV, which begins here as warmth and humour and will be tested to breaking point in Khazad-dûm — and the meteor that crashes at the end, bringing the mysterious Stranger to the Harfoots. Morgoth is gone, but his lieutenant is not, and the alliances formed in this first hour must hold against him now.

2. Season 1, Episode 6 — “Udûn” (30 September 2022)

If the premiere is the show’s thesis, “Udûn” is its first proof of spectacle on a scale to rival anything on television. The battle for the Southlands finally erupts: the Men of Númenor land in Middle-earth and ride to the rescue, Galadriel and Halbrand fight side by side, and Adar‘s long plan clicks into place. A dam breaks, water floods a channel of fire, and a mountain explodes. When the ash clears, the Southlands are gone — and in their place stands Mordor.

Why it is essential: This is the birth of Mordor, the land Sauron will rule in Season 3, and the episode where Halbrand earns Galadriel’s trust completely. She begins to believe he might be the lost king of the Southlands — and knowing what comes next, that trust is almost painful to watch.

What to watch for: The title is Sindarin for “hell”. Adar fights not for conquest but for a home for his Orcs, and the volcano — Orodruin, Mount Doom — is triggered by a simple sword-key and a broken dam.

How it sets up Season 3: Mordor is now Sauron’s seat of power, with Barad-dûr rising over it, and Adar’s Orcs are the same Orcs Sauron will now command. Númenor, having bled for Middle-earth, will never walk away from it again.

3. Season 1, Episode 8 — “Alloyed” (14 October 2022)

The Season 1 finale, “Alloyed”, is the single most important episode of the series so far. In Eregion, the Elven smith Celebrimbor forges the Three Rings for the Elves with the help of a gifted stranger. Then, in one of the great reveals in modern fantasy television, that stranger is unmasked: Halbrand is Sauron. He helped forge the rings precisely so he could corrupt them, and Galadriel — who brought him to Eregion, who fought beside him, who trusted him — is left shattered.

Why it is essential: Everything in Season 2 flows from this hour — Sauron’s new identity, the forging of the Seven and the Nine, Galadriel’s guilt, Elrond’s suspicion. If you only rewatch one episode from Season 1, make it this one.

What to watch for: The forging itself. Celebrimbor cannot make the alloy work until Halbrand suggests combining mithril with gold and silver from Valinor — a small, helpful idea hiding a terrible purpose.

How it sets up Season 3: Sauron returns in Season 2 as Annatar, the “Lord of Gifts”, and finishes his work on the rings. In Season 3 he will forge the One Ring itself. Galadriel enters the new season carrying the knowledge that she helped the Dark Lord — and that guilt will drive her choices.

4. Season 2, Episode 6 — “Where Is He?” (19 September 2024)

The quietest episode on this list is also one of the most consequential. “Where Is He?” is the calm before the storm of the Season 2 finale, bringing three storylines to a head at once. In Númenor, Queen Regent Míriel survives a trial by the sea her enemies expect to kill her — a moment the Faithful read as divine approval. Elendil says a painful goodbye to his daughter Eärien, who has sided with the usurper Pharazôn. Meanwhile the Stranger studies with Tom Bombadil, and in Eregion Sauron traps Celebrimbor inside an illusion to force the forging of the Nine Rings for Men.

Why it is essential: The Nine Rings are the most dangerous rings ever made — the ones that will turn nine great kings of Men into the Nazgûl, the Ringwraiths. This is the episode where they are born. It also locks in Númenor’s civil war, which will shape Season 3 as much as anything Sauron does.

What to watch for: Celebrimbor’s illusion is the clearest picture the show has given of how Sauron works — not with armies first, but with lies that feel like help. He makes Celebrimbor believe the forge is thriving while Eregion is already under siege.

How it sets up Season 3: The Nine Rings are finished and waiting for their bearers, Númenor is split with Pharazôn on the throne, and the Stranger is one lesson from becoming the wizard Middle-earth needs.

5. Season 2, Episode 8 — “Shadow and Flame” (3 October 2024)

If you watch only one episode before Season 3, watch this one. “Shadow and Flame”, the Season 2 finale, is the largest and most devastating hour the show has produced. The Siege of Eregion reaches its bloody end as Sauron’s Orc army overruns the Elven city. Celebrimbor, tortured and broken, defies Sauron to his last breath rather than surrender the rings. In Khazad-dûm, King Durin III tears off his Ring of Power and sacrifices himself fighting the Balrog, leaving Durin IV a king with a contested throne. The surviving Elves find a hidden glen where they will found Rivendell. And in the episode’s most joyful moment, the Stranger finally learns his name: he is Gandalf.

Why it is essential: This is the episode Season 3 picks up from. The five-year time jump begins in the wreckage of Eregion, and every alliance, grudge and ring in Season 3 traces back to this hour.

What to watch for: Celebrimbor’s defiance is the moral heart of the episode — he tells Sauron the rings he made will be his downfall. Durin III removing his ring is the only moment a Ring of Power is willingly given up — and the founding of Rivendell closes the episode on hope.

How it sets up Season 3: Sauron must now forge the One Ring, Durin IV must hold a divided kingdom, Númenor’s coup is complete — and Gandalf, newly named, is ready to take his place in the fight.

Bonus: The Season 2 Premiere Prologue — “Elven Kings Under the Sky”

If you have time for one more scene, watch the cold open of the Season 2 premiere (29 August 2024). It shows Sauron, in his fair form, betrayed and killed by Adar and the Orcs, his spirit reduced to a crawling darkness that slowly reforms itself until it can take the shape of a man — Halbrand. It explains Sauron’s relationship with his followers: he does not love the Orcs, and they do not love him. He uses them — and in Season 3 he will rule them openly.

What to Remember Before Rings of Power Season 3

Here is the whole story so far:

• The rings: Three for the Elves, Seven for the Dwarves, Nine for Men — all forged. Only the One Ring remains, and Sauron will make it in Season 3.
• Sauron — once Halbrand, then Annatar — now rules Mordor from the newly completed Barad-dûr, with the Orcs under his command.
• Galadriel knows who Sauron is and helped him once. That guilt follows her into Season 3.
• Elrond founded Rivendell after the fall of Eregion — the last safe haven of the Elves, alongside Lindon and Khazad-dûm.
• Durin IV is the new king of Khazad-dûm after his father died fighting the Balrog, but rival Dwarf-lords already challenge his throne — and the Balrog is only buried, not beaten.
• Númenor is in Pharazôn’s hands, with Míriel and Elendil on the losing side of a civil war. The Stranger is Gandalf, and the Harfoots return in Season 3.
• Jamie Campbell Bower joins Season 3 in a new role — but his character has not been officially named anywhere.
• Season 3 begins five years after the fall of Eregion — expect new alliances, new grudges, and a changed Middle-earth.
