You want to know that what Revan really accomplished as a Sith. Here is some useful information:
Creation of a Sith Empire:
A Sith Empire was founded by Dark Lord of the Sith - Darth Revan, and his apprentice, Darth Malak, as a dark side organization in direct opposition to the Galactic Republic and its Jedi defenders. Built upon a hardened core of veterans from the Mandalorian Wars and a host of Jedi converts, the fledgling new galactic power very nearly succeeded in conquering the Republic during the Jedi Civil War. During the Sith Empire's height, the Empire governed a large swath of the Outer Rim, including much of what was formerly known as Sith Space.
Known member worlds of Revan's Sith Empire:
- Dxun
- Korriban (Capital)
- Lehon
- Malachor V
Command Centre of Revan's Empire:
- Star Forge
Additional Strategic Establishments:
- A military base in Manaan
Known Allies:
- Czerka Corporation
Creation of a Sith Military:
Upon their return to known space, the Sith were well equipped for battle. The new Sith Empire's fleets were primarily dominated by stolen Republic vessels during the early stages of the Jedi Civil War, but they were soon supplemented by a host of starships built by the Star Forge. The Star Forge itself served as a primary staging ground and command center.
Naval/Space Fleets:
Interdictor Class Cruisers: Such as the Leviathan were among the finest Republic vessels of the time period.
Republic cruisers: Ravager type ships were also in service.
Sith Combat Fighters: Were a strange hybrid of technologies created by the Star Forge.
Sith Freighters: Were also used throughout the Empire. They were equipped with rudimentary defenses and possibly served as bombing craft.
Army/Ground Forces:
Sith Officers: were the army and naval troops of the Military.
Sith Troopers: served as the shock troops of the army.
Dark Jedi: were Jedi converts that formed the backbone of the Sith ground forces.
Sith Assassins: were used exclusively to hunt, capture, or kill Jedi.
War Droid-series: Various forms of battle droids were mass produced by the Star Forge for attack and defense purposes.
Revan's Dominance:
- The Jedi Civil War:
With Darth Revan at the helm, the Sith invasion was all but unstoppable. His Sith Assassins secretly flooded into the Republic from their base on Malachor V, killing and/or abducting Jedi throughout Republic space. In Sith outposts on Lehon, Dxun, and Korriban, Revan's most faithful servants broke captured Jedi and led them to the dark side. The Sith conspired with Czerka Corporation, one of the richest and most powerful galaxy-spanning companies of the time, to amass much needed resources. They also secured a place on the ocean planet of Manaan, thanks to the native Selkath neutrality, and so were able to export the healing agent kolto to their forces.
As the Sith's conquest continued unchecked, worlds began to secede to the Sith invasion fleet voluntarily, either out of fear of what had happened to Telos IV or because they believed that the corrupt and ineffectual Republic was finally about to fall.
- The Rakatans:
Revan also dominated and manipluated an ancient warrior race called "Rakatans" in their home world of "Lehon" and gained control of the Ancient Rakatan Temple, which held the secrets of the Star Forge and consisted of a very powerful Shield Generation Mechanism for the Star Forge to protect it from the external threats.
He alone wiped out an entire army of Black Rakatans and gained their ultimate respect and eliminated their threat to the Ancient Rakatan Temple. He also manipulated the knowlegeable "Elder Rakatans" to learn about the secrets of Ancient Rakatan Temple and tricked them to provide him entry in to the Temple. In this manner Revan established a strong foot-hold in Lehon planet by posting many Dark Jedi and Droids to protect his new and important post from external threats in Lehon.
Revan's unique creation:
- HK-47 Assassination Droid: HK-47 was a Hunter-Killer assassin droid and Jedi hunter built by Revan towards the end of the Mandalorian Wars. The Droid was constructed to kill those who Revan believed would destabilize the Galaxy. HK-47 proved to be one of the most successful assassination Droids in Star Wars history.
Revan's Notable Kills:
- Mandalore The Ultimate: The leader of the Mandalorians in KOTOR period and most powerful warrior among the Mandalorians. Despite being very powerful and heavily armed, he was no match for Revan in a single combat.
- Yusanis: The most powerful Echani Warrior ever known. His precognition capabilities were even superior to that of Jedi and he never lost a fight in fight in his life until he challenged Revan. Despite his own impressive abilities, he fell to the powers of Revan.
Additionally Revan killed many Mandalorian warriors, Jedi, Politicians, Rakatans and Sith Opponents.
