Before I start this new story I want to make something clear so I will capitalize and underscore for emphasis. THIS IS NOT A PLAGIARIZED VERSION OF SkyleafAlchemist19'S All That Remains! I have already spoken to her prior to posting this, and she has given me permission to use the assassin aspect of her story for mine! DO NOT I repeat DO NOT review this only to flame and accuse me of plagiarizing her story! She is ready to speak out on this issue if it does happen, and I thank her so much for doing so! The ONLY aspects of this story that will be the same is the assassin theme, and the use of the name Esgal as Legolas' alias, which she has also given me permission to use! So please dear readers, DO NOT POST REVIEWS ACCUSING ME OF PLAGIARIZING WHEN I HAVE CLEARLY EXPLAINED MYSELF IN THIS LITTLE SECTION!

Inspired by: SkyleafAlchemist19's All That Remains and Throne of Glass by Sarah J. Maas.

Summary: Legolas does not know how he came to be at Dol Guldur. He has no recollections of his past. Trained by the Witch-King of Angmar, the Elf becomes the Nazgûl Lord's personal champion. The assassin known as Esgal...

For Whose Sake

xXxXxXxXxXxXxXx

Father & Son I

Ennorwen lived on the outskirts of Mirkwood in a secluded house. The Elleth was banished from the palace after an incident involving an infant Lalaith that nearly cost the princess her life. Thranduil exiled her instead of execution, partly because the Elvenking knew the healer had done all she could to cure the infant from whatever it was that ailed her at the time. Legolas stumbled upon her home during an attack caused by the curse. That's how they became acquainted with one another.

"Ennorwen? Are you there?" Legolas called, sliding off Hagalith's back and leading his stallion towards the small wooden post.

The door creaked open to reveal Ennorwen, clad in a green robe, standing behind with a bright smile on her face.

"Esgal! I was wondering when you were going to visit," she beckoned for him to enter.

Legolas lowered his head as he entered, inhaling the familiar scent of juniper that always clung to his friend's body. Her house was just as he remembered. Plants scattered about in every direction, with some being tended to in the garden. The kitchen too, was so littered with plants, Legolas wondered how his friend could even prepare her meals.

"How fare you?" he inquired, taking a seat at the table.

The Elleth busied herself with brewing a pot of tea for them both. "Same old. Tending to plants is all I live for now, though some of my kin from Mirkwood visit from time to time. However they have to do it in secret though, since King Thranduil forbade anyone from visiting an exile like me."

The assassin could tell his friend was still hurt over what happened six hundred years ago. Though he was not there when it occurred, the Elleth did tell him what happened that caused Thranduil to exile her from the palace.

"Perhaps one day Thranduil will invite you back to the castle. Your talents are wasted here in this house."

"You humor me so," she poured him a cup.

Reaching into his pouch to pull out the vial, Legolas placed this on the table in front of Ennorwen. The Elleth took one look and immediately understood why he was here of all days.

"Your curse is acting up again is it not?" she questioned softly, closing her fingers around the cool vial.

"I was...in Imladris when it happened," Legolas admitted.

"Imladris? Why were you in Lord Elrond's domain? Did you not tell me you do not wish for others to...discover you?"

"I have made friends with Glorfindel," the Ellon took a drink of tea.

"You? Made friends with one of the Vanyar? Glorfindel no less!? Valar must be coming to an end for you to make friends with others, especially an Elf-Lord of high standing like Glorfindel himself."

Legolas couldn't help but chuckle at the tone she used.

"You hurt me so. Am I really that unapproachable?" Legolas mocked, placing a hand over his heart.

"You were the one who told me you wished not for others to know about you," Ennorwen disappeared into the kitchen briefly, returning with a pestle and mortar to grind herbs with.

Next she went through several different plants, selecting the ones she needed, and began the tedious task of grinding them into a powder. In essence the Elleth stumbled upon this medicine by accident. When Legolas first arrived at her doorstep in pain, instincts called for her to give him the very medicine she was currently making. It wasn't until later on that he told her about the curse, and how her plants help suppress the effects whenever it would act up.

"You know I do not wish to be discovered," he said softly.

"Because you were raised in Dol Guldur as the Witch-King's champion. Because you are afraid others will shun you for who you are. You are afraid you will become an outcast, never to be accepted despite being an Elf."

The silver-haired Elf did not respond, for what Ennorwen said was correct.

"I was lucky...lucky enough that Glorfindel accepts me for who I am..though I did not reveal I hail from Dol Guldur. I must return to the Witch-King's side after I depart here. The curse acting up means he is aware I am straying from my path, and I do not wish to incur his wrath," Legolas said.

"The medicine will be finished soon. You may rest while I prepare it," was all Ennorwen said before she went into the room connected to the kitchen.

"Ada!" Aradhel burst into the chamber his parents shared, coming upon his father being dressed by his mother.

"Goheno nin Ada," the crown prince said when he realized what was going on.

"Aradhel my child, what in Arda's name would possess to you barge into our chamber like this?" Edlothiad chided, helping her husband with his silver robes.

"Scouts have reported activity coming from Dol Guldur! Fell Beasts swarm the air above the Black Fortress. I am afraid there may be an attack upon our borders soon," Aradhel reported.

Thranduil studied his son with a look that sent even his wife into confusion. The Queen of Mirkwood had never seen her husband bear such a look of...hatred and animosity towards his own children before.

"I will handle this. You are dismissed," Thranduil eventually said.

"But-"

"Do not make me repeat myself!" the Elvenking roared.

Aradhel bowed stiffly, turning sharply on his heels and then departed the room.

"My dear, what is wrong? You were looking at our son with a peculiar expression."

The Elvenking sighed heavily, turning to face his wife of a thousand years. Thranduil loved Edlothiad, that much was true, but ever since the dream with Rívis telling him their beloved Legolas was still alive, the Sindar had been on edge. Were he to find his missing son, and reinstate him as the true Crown Prince of Mirkwood, how would his other children react?

"I believe Aradhel is becoming Shadowed," he confessed to his stunned wife.

"Aradhel? Shadowed? What do you mean?" she gripped his forearms tightly.

"His aura is tainted with Darkness, and it is growing ever since the encounter with that mysterious Elf called Esgal. I believe our son still holds a grudge against Esgal for Aeneth's death."

"But...for Aradhel to be Shadowed..." Edlothiad lowered her head in shame.

Thranduil placed a finger under her chin, gently lifting her head until their eyes met. He could see she was fighting back tears that were brimming around the edges. He could also see the love and kindness she had for him, even though she knew of his undying love to his first wife.

"I will not exile him my love. I will ask Lady Galadriel and Lord Elrond for their help. Though I do not wish to ask for their aid, I cannot stand by and watch as my realm is swallowed by the Darkness anymore. Mirkwood may not be as powerful as we once were, but I swear that as long as I live, I will not allow anymore harm to come to our children. Losing Legolas was hard enough. If I lost another..." Thranduil trailed off, unable to go on at the thought of his missing son.

"Do not fear my love. I will be with you until the very end," Edlothiad slipped her arms around his waist.

The Sindar embraced his wife silently, tears awash upon his pale face.

It was a little past nightfall by the time Legolas made it back to Dol Guldur. Now that Ennorwen had replenished his supply of medicine, the assassin was no longer afraid of the curse acting up. This time the Elleth had prepared two extra vials, so it should last him quite nicely.

"Lord Esgal," Fixx nervously bowed as the Elf arrived at the entrance.

"Where is the Witch-King?" Legolas did not bother looking at the Goblin, ordering Hagalith to march right past.

"I-In his tower!"

Dismounting in a fluid motion, the Ellon turned his head, waiting for the Goblins to take the reins. Fixx and his companion came forth without hesitation, guiding the stallion away towards the stable where Hagalith had his own stall, separate from the Wargs.

"If anything happens to Hagalith, I will have your hides," Legolas threatened.

"Yes Lord Esgal," the two Goblins bowed and hurried away.

"I have returned," Legolas said, kneeling before the Witch-King as the Nazgûl faced the window in the tower that overlooked the border to Mirkwood.

"What of your missions?" the Ringwraith rasped, not turning to look at his champion.

"Arathorn is dead. As is his wife Gilraen."

"What of the child?"

Legolas lowered his head. "The child...lives."

The Witch-King lashed out angrily with his powers, striking Legolas directly across his chest. Blood began to seep from the wound, soaking through his tunic rather quickly. Pressing a hand against his chest, the assassin did his best not to wince as he returned to a kneeling position.

"You allowed Isildur's heir to live! The Necromancer demands the end of Isildur's line! Esgal, I have trained you better than this."

"Forgive me my master," was all Legolas managed to say.

The Nazgûl turned to face the kneeling Elf. "Denethor is no longer your concern. Gondor will fall soon, and Rohan will follow. All of Middle-Earth will soon belong to Master Sauron, and my kingdom of Angmar shall rise once more!"

"Thorin and his company are dead?" the assassin struggled to his feet.

"Azog will assure the death of Thorin before he ever reaches the Lonely Mountain. Erebor is not a concern, and I am wise enough to avoid Smaug's wrath."

Legolas felt his vision begin to blur.

"You have one chance to redeem yourself Esgal. Follow me as I march upon Mirkwood's borders. When we arrive, you will personally slay that wretched leader of theirs, and present his head to me. If you do this, I will lift your curse. Should you fail...the consequences will be far worse."

"As you command, my master."

"Return to your room and bandage yourself. The wound is not deep enough to hinder your usual movements," the Witch-King said.

The assassin slowly limped away from the room.

Only when he was in his room did Legolas realize the Witch-King was lenient with his punishment. Normally when he failed a mission, he would suffer at least a whipping followed by agonized enduring of the curse. For the Nazgûl to forgo his punishment so easily was a first for the assassin.

Carefully peeling off his tunic, silver eyes fell upon the gash across his chest. The bleeding had stopped, though it left trails behind in its wake. Going into the washroom, he took a wet towel and gently cleansed the wound of dried blood. Next he took out a roll of bandages, and began to cover his chest. It would be a lot easier if he had help, but Legolas was used to doing things on his own.

Once secured enough, the assassin rummaged around the wardrobe until he found a new tunic that he had bought on a previous trip to one of the villages. Slipping this over his head, the Ellon headed for the stables after hearing the unmistakable cry of the Nazûl.

It was time to strike.

"Sound the alarms! We are under attack!" Hethurin shouted, being the first to spot the large army marching towards them from the direction of the Hill of Sorcery.

"What is going on?" Arastor was the first to arrive.

"It is the Nazgûl and his army," Hethurin pointed a finger at the army.

"Strengthen the borders! Send every available soldier we have to defend our eastern walls! We cannot allow Mirkwood to fall today," the second prince ordered.

Soldiers from everywhere scrambled to position themselves over the wall.

Thranduil soon arrived, clad in his silver armor."

"Ada," Arastor bowed.

"King Thranduil," Hethurin mimicked the prince's movements.

"So he comes," the Elvenking stood at the edge.

Archers were lined up at the wall, holding their bows tightly, nervously waiting for orders from their king to fire arrows into the ever-growing army. This was the first time many of them had ever experienced such a scene as this. The closest they had ever come to was fighting off Spiders.

Their very lives were at stake.

"Your orders my king," Arastor said.

Thranduil narrowed his eyes. "Not yet. Tell everyone to don their armor! We are riding out to meet them," he commanded, departing to the stables himself.

Hagalith trotted next to the Witch-King, the Ringwraith flying in the sky on the back of its gigantic Fell Beast. Behind him trailed an entire army of Goblins and Orcs, all lusting for blood and action. The assassin did not expect an attack so soon. A part of him was anticipating the battle between himself and King Thranduil, but another part of him whispered it wasn't right.

Legolas held a hand out when the Ringwraith landed the Fell Beast.

Moments later he could make out silhouettes in the forest, with the shadows becoming clearer as they reached the clearing. The assassin saw Thranduil was leading his army, riding atop a deer with great antlers.

Behind him were Elves clad in golden armor.

"Begone foul creatures of Mordor! Mirkwood will be tainted by your Darkness no longer!" Thranduil declared loudly, drawing his sword while his army simultaneously drew arrows as one.

"Today Mirkwood shall become a part of Dol Guldur! Go forth my champion, and bring me the head of Thranduil Elvenking!" the Ringwraith commanded.

Legolas walked forward after dismounting Hagalith.

"You..." Thranduil murmured as Legolas stopped in the center of the forest.

"Goheno nin King Thranduil. I must obey my master's command as his champion," the assassin drew forth his blades.

"Ada, allow me to face him," Aradhel said, urging his horse forward.

The Sindar held a hand out. "No ion-nin. This is my fight alone," he answered.

"You cannot!"

"Silence! Do not disobey me!"

The two Elves faced one another. Legolas kept his eyes trained upon the sword in Thranduil's hand, while slowly circling him like a wolf would its prey. As much as he wanted to set Thranduil free and not slay him, the assassin could not disobey his master.

Not with so many eyes watching his every move.

"May the Valar watch over you," Legolas whispered.

Then he struck.

To be continued...

Review?

Bahahaha, I am evil for leaving it at a cliffy.

You'll have to wait for the next chapter to see who wins.

Thranduil? Or will it be Legolas?

Will Legolas discover that Thranduil is his father?

Until next time!
