How Theo Became a Ringwraith in Rings of Power Season 3, Episode 4—and What Happened Next

Theo’s transformation begins

Theo’s long-standing resentment over his absent father gives Sauron a way to influence him. Using necromancy, Sauron offers answers and claims Theo’s mother murdered his birth father, though the story says that accusation may not be true.

Sauron’s response suggests Theo’s noble ancestry and magical abilities are genuine. That heritage convinces the Dark Lord to make Theo the next Ringwraith.

A Ringwraith not fully lost

The Nazgûl are called “Nazgnagôl” in season 3 and have not completely succumbed to the darkness of the Unseen World. Theo therefore keeps his face and some free will.

War reshapes the wider conflict

Five years after Eregion’s fall, Sauron is forging the One Ring as war with the Elves intensifies. The surviving strongholds of Lindon and Rivendell rely on the Three Rings, while Durin IV supplies weapons to the Elves.

In the premiere’s final hour, Galadriel and Arondir free Celeborn from an icy prison, then face Sauron and a new assistant. Thrain takes the throne in Khazad-dûm, while Elrond, Gil-galad and Círdan seek help from Númenor.

Númenor’s pressure and Marnûkh

Ar-Pharazôn’s rule faces resistance from the Faithful, and his treatment of mortals on Middle-earth’s shores helps drive Southlanders toward Sauron. The Faithful also take his son prisoner, drawing his attention away from the Elves’ request for aid.

Marnûkh’s apparent defection raises questions about his motives, including whether he intends to take Galadriel’s ring. His death ultimately makes his break with Sauron clear; the account also cites Adar’s killing and heavy losses against the Elves as factors behind the switch.
