Plot

Arondir finds himself a captive. Galadriel and Halbrand explore a legendary kingdom. Elendil is given a new assignment. Nori faces the consequences.

The captured Arondir is taken to an Orc construction camp where other captives are digging trenches somewhere in the Southlands. These allow the Orcs, who are sensitive to sunlight, to move during the day. Arondir finds his fellow Elves Médhor (Augustus Prew) and Revion (Simon Merrells) have also been brought there, and they begin planning their escape. When Revion refuses to cut down a tree in their path, the Orcs kill Médhor. Arondir agrees to cut down the tree. He sees that the surrounding area has become poisoned and desolate. Arondir believes that the Orcs are searching for something, due to which they pillage village after village. The prisoners discuss that perhaps Morgoth has a successor and his name is Adar, which is a Elvish name.

Galadriel and Halbrand are picked up by a ship captained by Elendil (Lloyd Owen) who takes them to Numenor, an island kingdom ruled by Men. The Men of Numenor stood with Elves in the battle against Morgoth, while the Men of middle earth supported Morgoth. After the war, the Valar granted the Island of Numenor to the Men as a reward. For many centuries, Elves were welcome in Numenor. But eventually, Numenor began to break all contact with the Elves and it was never clear why. Relations between the island and the Elves have grown strained, and Queen Regent Míriel (Cynthia Addai-Robinson) denies Galadriel's request for a ship back to Middle-earth. Miriel is also not happy with Elendil for bringing Galadriel to Numenor and questions his loyalty to the Kingdom of Men. Elendil is assigned to watch over Galadriel and he takes her to the kingdom's Hall of Lore. Galadirel is astonished that many Men in Numenor still speak Elvish. Galadriel learns that Miriel's father was loyal to the Elves and was deposed due to this. He is now a captive in his own kingdom. They discover that the mark of Sauron is actually a map of the Southlands, where a new realm for evil forces is planned, by the successor of Morgoth. Galadriel believes that Sauron has now returned.

Halbrand gets into a fight with some Númenóreans and is imprisoned. Galadriel finds him and reveals that she knows he is the true king of the Southlands, descended from the Man who united the tribes of the Southland and was loyal to Morgoth. She asks him to return to Middle-earth with her to redeem both of their bloodlines. Galadriel's family started the war and Hallbrand says that his family lost it. Meanwhile, Elendil's son Isildur (Maxim Baldry) nears the end of his training as a naval cadet, but has been encouraged by his brother Anárion to postpone his graduation against Elendil's wishes. Elendil wants Isindur to join the Navy as a full time sailor and not as a trainee cadet. Earien (Ema Horvath) is Isildur's sister.

The evening before the Harfoots' next migration, the Stranger accidentally reveals himself to the rest of the Harfoots while trying to read some star maps that Nori stole for him from Sadoc. Nori reckoned that the Stranger was looking for a specific constellation and that they could only find it in Sadoc's map, which were very detailed as Sadoc is an avid astronomer. The shocked Harfoots consider exiling Nori Brandyfoot for helping the Stranger, but she is forgiven because of her young age. The next day, the Harfoots start migrating and the Brandyfoots struggle to keep up due to Largo, Nori's father, who has an injured ankle. The Stranger follows them, and helps them with their cart.

Arondir, Revion, and some other captives attempt to escape from the Orcs when the sun is highest. The Orcs send a Warg to attack them, which Arondir kills. Revion makes it out of the trench but is killed by archers. Arondir is unable to get free and is brought before the mysterious leader of the Orcs, Adar (Joseph Mawle).
