All the Nazgûl are named - The Witch-king of Angmar, The Dark Marshal, Khamûl The Easterling, The Betrayer, The Shadow Lord, The Undying, The Dwimmerlaik, The Tainted and The Knight of Umbar.
The Quenya word for Nazgûl is Úlairi. Their leader is known as The Witch-King of Angmar. The only one of the Nazgûl whose name is given by the Tolkien is Khamûl.
The Witch-king of Angmar, also known as the Lord of the Nazgûl, was the leader of the Nazgûl (Ringwraiths) and Sauron's second-in-command during the Second and Third Ages of Middle-earth.
The Lord of the Rings calls them Sauron's "most terrible servants". Their leader, known as the Lord of the Nazgûl or the Witch-king of Angmar, had once been the King of Angmar in the north of Eriador.
As one of the nine Nazgûl, Isildur was forced to serve the Dark Lord for all time until he was defeated and freed by Talion. The ranger later claimed his ring to survive after Celebrimbor abandoned him and eventually took Isildur's place among the Nazgûl after holding back Sauron's forces for decades.
Aragorn was a Ranger of the North, first introduced with the name Strider and later revealed to be the heir of Isildur, an ancient King of Arnor and Gondor.
However, he does not possess the ability to live forever, and he cannot choose to be mortal or immortal like Arwen, the half-Elf he loves and eventually claims as his wife. Because Aragorn is mortal and Arwen chose to remain in Gondor and become mortal, their son, Eldarion, is mortal as well, despite his Elven lineage.
The Nazgûl, as servants of Sauron, feared the power of Ulmo, and believed that some of his power might still flow through the waters of Middle-earth, hence why they avoided it as much as they could.
The Nazgûl were nine Kings of Men who were given rings of power by Sauron.
1. Talion becomes a Nazgul. The biggest bombshell from Shadow of War comes at the end when we learn Talion's ultimate fate: Talion becomes one of the Nazgul. After he's abandoned by Celebrimbor, Talion begins to die.
The Witch-king is the most powerful of the nine ringwraiths, having served Sauron as a Nazgûl for more than four thousand years. The Witch-king has a particular hatred of Gondor, and is responsible for the death of Gondor's final king, Eärnur.
Éowyn killed the Witch-king of Angmar in The Lord of the Rings: The Return of the King, but the movie leaves out some important details about how she did it when the Witch-king is more-or-less immune to mortal weapons.
In Middle-earth: Shadow of War, Helm is shown to have become a Nazgûl. He received his ring from Sauron and Celebrimbor after he was mortally wounded in an ambush by Wulf's men, during which his daughter was kidnapped.
Instead of subduing him with his own ring of power, Talion chose to spare Isildur and release his spirit, allowing him to proceed into the afterlife after millennia of service to Sauron. Talion took Isildur's ring and eventually became a Nazgûl himself.
The Nazgûl Sisters, known as Riya and Yukka are the main antagonists in Middle-earth: Shadow of War story expansion, The Blade of Galadriel. They were once daughters to Emperor Sagong of the Kingdom of Shen in the farthest east of Middle-earth. These powerful warriors were sent to Mordor for conquest by their father.
The Shadow Lord is one of the unnamed Nazgûl who begins as a veiled Nazgûl but can transform into different forms depending on the player's choice. The Nazgûl's powers are tied to Sauron as they do not have levels of their own but gain power and unlock new abilities as Sauron regains his power of old.
Fran Walsh, Peter Jackson's wife and screenwriter of all 6 Middle-earth films, is the voice of Nazgul screams.
After Isildur's (voiced by Nolan North) death, the Orcs brought his body to the diminished and vengeful Sauron, who put a Ring of Power on his finger, reviving him as one of his servants and eventually turning him into a Nazgûl.
The Witch-king, the Lord of the Nazgûl, used one such Morgul-knife to stab Frodo on Weathertop.
The Nazgûl (Black Speech: Ringwraiths, sometimes written Ring-wraiths), also known as the Nine Riders or Black Riders (or simply the Nine), were Sauron's "most terrible servants" in Middle-earth. They were mortal Men who had been turned into wraiths by their Nine Rings of power.
During their approach on Weathertop, they're described as "vague shadowy shapes" and "So black were they that they seemed like black holes in the deep shade behind them." So while it's possible they still have their cloaks on in these moments, the descriptions suggest they are nothing more than shadowy black figures ...
Most of their vision is based on light, but details are all a blur to them. This is how they managed to spot the hobbits after they lit a fire in The Fellowship of the Ring. If someone were to put on the One Ring, however, the Nazgûl would be able to see them clearly, as they did when they stabbed Frodo.
Elrond has only Half-Elf, and he was once given the choice to be counted among Man or Elves. When he chose to be counted as Elven kind, he was then given immortality. Because Arwen is Elrond's daughter and also Half-Elf, she too has the choice to be a mortal woman or an immortal Elf.
One year after Aragorn's death, Arwen dies at the age of 2,901.
Princess Arwen Evenstar gave her beautiful necklace to Aragon to pledge her eternal love to him. This special gift from an immortal elf to a mortal man symbolized Arwen's decision to forsake her immortality to be with the person she truly loves.
