Since the other one is pretty weird, I decided to make a new one
I'll do it like Sabre did if I may....
WorldsCoruscant:
After the fall of Coruscant, The greedy Siths began to shape Coruscant with their own designs, and this included the installment of thousands of surveillance systems throughout the city world. Massive shield generators were placed all over Coruscant, and where they overlapped, severe storms took place, giving the planet a gothic look, which mirrored the utter desperation of many of its inhabitants as they choked under the Sith iron rule
Korriban:
The Sith Lords erected huge palaces and burial complexes on the scorched earth of Korriban. But these giants structure were even dwarf by the gargantuan Sith Academy that is tremendously well protected by massive turbolaser batteries and legions of Elite Sith Soldiers making any attempt to infiltrate it, impossible.
Ziost:
The fortress of Naga Sadow that stood as a immense stronghold of Iron and stone was quickly turned into an academy by the Grand Admiral of the Sith Empire himself, Darth Invidius. The planet surface is dotted with heavy weapons emplacements capable of piercing through the shields and hulls of enemy vessels
Yavin:
The ancients massassi Temple, tainted in the Dark Side of the Force were even more profane and fiendish when one of the strongest Lord of the Sith, Darth Brenos took the planet for himself using the planets darkness to even further is everlasting fall into the Dark Side of the Force.
AlliesThe Trade Federation: With the assistance of the Trade Federation, the battle to gain Coruscant the first time was made easy, with the extra ships and weaponry given to the Empire from their arsenal. They also supply the Empire with battle droids and droidekas.
The Techno Union: A band of powerful robots, the Techno Union has helped the Empire with supplies of their specialty droids, which have the incredible strength to fit in with the grand army of the Empire.
The InterGalactic Banking Clan: With the help from this clan, it has become far easier for the Empire to gain money, and use it wisely to invest in capital ships, fighters, and almost every kind of warfare possible. The cost of these arms went down greatly thanks to this clan.
The Trade Alliance: Lead by Keanu Cange, the Trade Alliance has helped in the past endeavours of the Empire by supplying us with extra fleets, extra resources and extra fighters with a taster for battle. They are an invaluable part of the alliance.
The Hutts Clan: With the Hutts running the crime syndicate, it has given the Empire the upper hand in this war. The Hutts have the knowledge on where the Jedi are in hiding, and give this news to the Empire in exchange for a few credits here and there. With the Hutts in the alliance, they also give the Empire the planets in their sector, such as Nal Hutta and Nar Shaddaa.
The Dematri Empire: Since their king and queen abandoned them, the dematri have ventured out of their home and now enhabit the skies in large space stations, manufacturing weapons of mass destruction for use with the sith. they currently inhabit the planet of Malastare, where devlen's ancient shipyards have come back into service. devlen redevoused with them there and took back his title.
Key Sith HerosDarth Viea:
Shes the strongest of the sith, 'nuff said.
Darth Careein:
The Empress wifes, shes pretty strong and stuff.
Grand Admiral, Darth Invidius:
Utterly and completely ruthless, he thinks nothing of killing, whether it be a filthy Jedi scum or another member of the Sith Order. He has a black, irredeemable heart. There's nothing that can be said about him that is good. With his legendary strategic ingenuity and flawless cunning it is not for nothing that the Empress gave him controls of the Sith Armada.
Lord of the Sith, Darth Brenos:
In his early life, Darth Brenos or Dexon Kyjar was the head master of the Jedi Order. His lightsabers skilled were unmatch and his uncanny talent negotiation was well known throughout the galaxy but the Dark Side of the Force soon took control over him, twisting him into the wretched creature that would become Darth Brenos. Unlike Lord Invidius, Brenos was not a merciless killer and prefer working in the shadows of the Empire striking only when the time was right and the action necessary.
Apprentice to the Empress and Lord of the Sith, Darth Ravinos:
A once noble Correlian Jedi Master, Kit Rendar was a Senior Member of the Jedi Council. With the Jedi Order doing nothing to prevent the disaster of the war, Kit took the safety of his beloved homeworld Corellia into his own hands. He went to Korriban and made a deal with the Dark Lordess that he would become her apprentice if she spared his homeworld. The Dark Lordess lived up to her end of the bargain and Kit became know to only a select few as Darth Ravinos.
He still kept up the facade of being a Jedi in order to inflict a heavy blow to the Republic and Jedi's image when he led Republic and Jedi forces in the attack on Pho Ph'eah under the lie that Sith had taken over the important Republic planet. After destroying most of the planet, Kit openly admitted to his troops that he was the Dark Lordess's Apprentice. His captain defied him and was made an example as Kit, now Ravinos, skinned him alive infront of his command crew. Ravinos now has fully fallen to the Dark Side and lives to serve his master and help her dominate the galaxy.
(this is from Kit profile by the way, I just added a few words )
Devlen Darkbroode: The Leader of the Dematri Empire, Devlen has returned to the sith and supplies them with deadly hexalon based weapons. Devlen himself is a cunning sith Warlock, his mastery of the darkside rivals the greatest sith lords, and his dematri influenced fighting style makes him a formidable swordsman
Keanu Cange: Leader of the Trade Alliance and an invaluable part of the Sith Empire. Keanu gives the Empire support with his Kuat shipyards and droid assistance, and helps greatly in every battle the Sith has been in.
