The coreworld of Coruscant rained like it hadn't in millennia.  Several battalions of the Coruscant Guard clones patrolled the perimeter of the Senate building.  Two clones discussed the recent events.

"Hear about Commander Zhara?  Apparently, he got killed by his  general's apprentice.  And Neyo? Heard he had his chip removed, so he saved his general long enough to see her die.  But hey, no Jedi is dumb enough to attack the Emperor here," he said as his comrade waved his hand.

"Shut it!  What's that?" the clone said as a dark figure approached.  He wore a tattered black robe with streaks of what looked like blood running down the skirt.  His dark grey armor had black streaks that could be recognized as lightsaber burns.  His cloak appeared tattered, weathered, and covered in blood stains.  His hooded head raised and they saw what appeared to be an ancient Mandalorian mask, save for a small part of the face that had been cut, revealing the man's right eye.  His eye flashed open, revealing his green iris and black eye.

"Sir, you may go no further!  If you mean to harm the Emperor, you'll need to have more than yourself to do it," a clone said as several squads of Coruscant Guard ran up and raised their weapons.  A chill went down their spines as he laughed sinisterly.

"Who needs numbers when you are Death itself?  You underestimate the power of the Force," the figure said grimly.

"Never mind, gents.  Kill the Jed..." the clone started but was stopped as he and his comrades were lifted off their feet.  Darth Nekros swiftly snapped their necks and dropped the bodies.  His boots barely made a sound as he entered the building.  As Nekros made his way through the building, he stuck to the shadows, finally reaching the lift to take him to Darth Sidious's office.

Emperor Palpatine sat at his desk working on paperwork when his Red Guards standing to the entrance of his office fell to the ground, dead.  A sinister figure in tattered black robes walked in.  "Emperor Traike, I expected Master Yoda to arrive.  This is unexpected, yet still of interest.  I sense a darkness in you that I haven't felt before," Darth Sidious said with a deep voice.

"Have I been abandoned by the Sith after all this time?  Has my knowledge been purged, unlike the Jedi Order?  Have my acts of cruelty,malice, and power been lost like the artifacts of old on Korriban?" Nekros said.

"What is it you are saying?" Sidious said as he stood to his feet.

"You do not understand.  but you will be made to.  The power to truly cheat death has been found by one alone, and he has come," Nekros said.

"He is no more.  He has been gone for millennia now," Sidious said.

"He stands before you now.  I am Darth Nekros, the Lord of the Dead.  I have come to retake my place as the True Lord of the Sith," Nekros said as he dropped his cloak to the floor.

"You are irrelevant and outmatched," Sidious said as he shot a barrage of Force Lightning at his opponent.  As the smoke settled, Nekros stood tall as he held his right hand out, lightning arcing off it.  Palpatine shot more lightning at him, but Nekros merely absorbed or redirected it away.  Palpatine turned to the door to flee, but Nekros was there, lightsaber drawn.

"Truly, I see now how your Master died.  You were too weak to face him like a Sith, so you betrayed him when he was weakest.  You killed him because of your weakness.  Pathetic," Nekros said as Palpatine drew his lightsaber and climbed on the Chancellor's platform into the Senate.

Nekros watched and he flipped upwards, landing on the floor some several dozen feet below the cowering Sith.  With one leap, he landed on an upper platform, staring down at his opponent.  He jumped off and gilded through the air dramatically.  Palpatine jumped across and positioned himself high enough for an advantage.  Nekros looked up and began chuckling grimly.

"I see you tactics.  You never learned to fight an opponent who could defend themselves, so you're trying to tire me.  I can last a year without sleep.  I can wait.  Can you?" Nekros asked, mockingly.

Sidious screeched as he lunged at Nekros.  Nekros blocked the attack with ease.  Sidious, in his age and wisdom, aim for Nekros's un-armorder elbow to severe it.  The lightsaber skidded harmlessly off the fabric.

"Do you really think I don't know about Armorweave?  Do you really think I'm that stupid?" Nekros asked, unimpressed.

This angered Sidious and he fought ferociously with both hands swinging for maximum strength.  His power and knowledge of the Force was no match for Nekros' considerably longer life and his body in his prime.  Nekros blocked the strikes with his left hand (yes, Bastun is right handed and Nekros is left handed.  I thought it looked better in my head so there).  Nekros swung at Sidious's lightsaber and stabbed the emitter, deactivating the weapon, causing the Sith to return to higher ground.  Because of the difficulty of his opponent, Nekros merely watched in amusement.  Sidious growled and shrieked as he began pulling senator platforms out of place and began throwing them at Nekros, who darted from platform to platform, dodging the steel objects. As one hit, Nekros caught it with his hands with ease, using the Force to augment his already superhuman strength.  Lifting it up, he hurled it up at Palpatine, who was hit hard and flung backwards.  He struggled to his feet, but was pressed down by the Nekros.  Nekros reignited his lightsaber and held the crimson blade near the Emperor.

"Tell me now why I should spare a weakling such as you?" Nekros said as the Sith before him whimpered.  Nekros drew his arm back to strike but was stopped as he was granted a vision.  He saw armies of soldiers in white march under the banner of the Galactic Empire.  He saw a dark room where he saw Palpatine assaulting a young man in black.  Behind him he saw a man in black armor grab Palpatine and throw him down a pit.  Nekros came back to the present, realizing that he had seen the vision before.  He stood up and swung a swift strike across Palpatine's hip, crippling him.

"Kill me.  My apprentice will, and you will be gone," Palpatine said.

"I think Vader will have other problems.  Your wound will hinder you, but you will never have a cybernetic replacement or else he will kill you," Nekros said as he turned to leave.  Nekros realized that he needed to rendezvous with Senator Bail Organa and Yoda on a medical center in the Outer Rim, where they were to await Obi-Wan's arrival after defeating Vader on Mustafar.
