Dol Guldur is located at the southern end of Mirkwood, originally a long-abandoned fortress.
But ever since the mysterious Necromancer occupied this place, a powerful dark force has enveloped the area, and dark creatures such as Orcs, specters, and giant spiders roam here.
It has become a demon's den, and no one dares to approach it.
On this day, Luke, Gandalf, Radagast, Elrond, and Glorfindel quietly arrived at Dol Guldur, avoiding the dense Orcs outside the fortress and sneaking into the interior of the fortress Castle.
All five of them had the Disillusionment Charm cast by Luke on them, so they did not encounter too much obstruction along the way.
However, the closer they got to the ancient Castle, the stronger the dark power became, making everyone's expressions more solemn.
"It seems we have been deceived all along," Elrond said, fully armored, drawing the elven sword from his waist, his expression wary and solemn, "The Dark Enemy has returned again."
The radiant Glorfindel also drew a magnificent long sword with wavy golden patterns covering its blade, instantly transforming from an elegant elven noble into a battle-ready warrior.
Luke, Gandalf, and Radagast also raised their respective wands and staffs, vigilantly scanning their surroundings for any danger that might appear.
The five entered the interior of the ancient Castle, looking around at the empty surroundings, not daring to relax in the slightest.
Gandalf was the first to act, heavily striking the ground with his staff and chanting a spell: "Evil hidden here, I command you to reveal yourself quickly!"
As the detecting magic halo spread around, the surrounding environment remained unchanged.
It was as if it was truly just an abandoned fortress Castle.
But none of the people present were foolish enough to be deceived by such an illusion; instead, they became even more vigilant.
After all, being able to hide from Gandalf's detection magic only meant that the enemy hidden in the dark was stronger.
Gandalf did not give up, continuing to use magic to detect, trying to force out the person hidden in the dark.
Suddenly,
The surroundings instantly became cold and dim, and a power filled with coldness and fear swept over, bringing a heavy sense of oppression that made breathing feel suffocating.
Nine armored specters appeared from the void; they were like ethereal shadows, with empty darkness inside their armor, holding morgul blades, and exuding a powerful dark aura.
They are the Nazgûl!
The Nazgûl were once nine of the most powerful human kings, whom Sauron, disguised as Annatar, Lord of Gifts, in the Second Age, gave nine Rings of Power infused with his dark power.
The Rings granted them near-immortal life, but they were gradually corrupted and fallen by the dark power within the Rings, eventually losing themselves and becoming servants of the Dark Lord Sauron, controlled by him.
The nine Nazgûl surrounded the group from all directions, and dark incantations like the language of the dead echoed in their ears, attempting to corrupt their minds.
"You should not have awakened!" Elrond said with authority, the elven sword in his hand releasing a powerful sharp edge.
Glorfindel radiated dazzling holy light; having bathed in the light of the Two Trees, the radiance around him contended with the surrounding darkness.
"Servants of Mordor, this is not your domain; you should return to the Unseen World!"
The Nazgûl were startled back by Glorfindel's radiance, but as if confident, they charged forward again, attacking the group.
Gandalf, Elrond, Radagast, and Glorfindel each dealt with two Nazgûl.
And the remaining Nazgûl, the Witch-king of Angmar, chose Luke as his target.
"We meet again, young Wizard; this time, you cannot escape." A sharp, low, spectral voice came from within the hollow, dark helmet.
Luke was facing a formidable enemy; without further ado, he waved his wand: "Bombarda!"
The dazzling spell passed through the Witch-king of Angmar's illusory body, as if it were merely an ethereal shadow.
The Witch-king of Angmar let out a low, triumphant laugh: "Wizard, your spells are useless against me."
With that, he raised his morgul blade and quickly slashed at Luke.
"Expecto Patronum!"
Sacred, bright, silvery-white mist gushed from the tip of the wand, condensing into a massive owl that spread its wings and extended its sharp talons, attacking the Witch-king of Angmar.
The owl Patronus was incredibly fast and agile, dodging the morgul blade and fiercely clawing at the Witch-king of Angmar's shoulder.
With a sharp, piercing shriek, a clear wound was torn into the Witch-king of Angmar's shoulder; the Patronus of white magic was naturally the bane of dark power, and the light-filled magic corroded the wound, causing him pain.
And the owl Patronus did not stop, continuing to attack the Witch-king of Angmar, leaving more wounds on his body.
Streaks of black mist dissipated from the wounds, continuously weakening the Witch-king of Angmar's power.
But as the chief of the Nazgûl, the Witch-king of Angmar was naturally not so easily dealt with.
Before the owl Patronus could leave too many more wounds on the Witch-king of Angmar, a morgul blade filled with evil cursed power pierced through the owl Patronus.
The owl Patronus let out a mournful cry and dissipated into silver mist.
The Witch-king of Angmar's hollow gaze fell directly on Luke.
"Wizard, I will pierce your heart with the morgul blade and transform you into my servant, a Nazgûl!"
With his Patronus extinguished, Luke's face was somewhat pale, but facing the aggressively attacking Witch-king of Angmar, he showed no fear or panic.
As he waved his wand, golden notes flew out, playing cheerful music.
This music, full of positive emotions, was inspiring and exhilarating fairy music for Luke's side.
But for the Nazgûl, it was uncomfortable noise that would disturb their thoughts and weaken their power.
For a moment, the tables turned, and Gandalf and the others quickly gained the upper hand, pressing the Nazgûl hard.
"Expecto Patronum!"
Luke cast the Patronus Charm once again.
An owl Patronus, far larger than before, almost comparable in size to a giant eagle, shot out from his wand.
The owl Patronus spread its massive wings, silver light streaming as it flapped, and it extended its sharp giant talons, striking away the morgul blade with one claw, then firmly grasping the Witch-king of Angmar and battling him in mid-air.
The giant owl Patronus and Luke were of one mind; it grabbed the Witch-king of Angmar and flew towards Luke, where a silvery-white spear with a gleaming, bright spearhead awaited the Witch-king of Angmar.
Luke held the divine spear Aeglos, and with the help of the Patronus, the divine spear directly pierced the Witch-king of Angmar's hollow, dark body.
The divine spear contained powerful destructive force, instantly tearing apart the Witch-king of Angmar's spirit form, causing him to vanish into thin air.
Having dealt with his opponent, Luke took a deep breath.
Seeing that the others were still fighting the Nazgûl, he quickly controlled his Patronus to attack the other Nazgûl, to lend a hand to his companions.
Soon, everyone dealt with the Nazgûl one by one.
However, feeling that the surrounding dark power had not diminished in the slightest, their expressions became even more wary and solemn.
Now that the servants had been dealt with, the next challenge would be to face their master behind them!
