The Great Force War

The Great Force War was a direct clash between the Jedi and the Sith, where their respective governments, the Galactic Alliance and Sith Empire, chose to stay neutral.

Prelude
Since the end of the Eternal Crisis, Jedi-Sith hostilities had remained high, and many Jedi and Sith died from just running into eachother on diplomatic missions. Tensions would rise, and see both the Galactic Alliance and Sith Empire step away from their affairs, the Sith Empire being under the rule of Darth Tylen, who advocated for peace between the Jedi and Sith, and the Galactic Alliance being under the rule of a council that advocated for Armed Neutrality. Eventually, in 295 ABY, all the tension that had built up culminated at the Skirmish on Mandalore, where Sith and Jedi diplomats ran into eachother, and both were backed up by a heavy escort due to the constant deaths of diplomats. 2 Jedi and 4 Guards died, while 1 Sith and 7 Guards were killed on the other side. The surviving Sith diplomat would arrive back at Yalen's castle on Dromund Kaas, where he reported the incident. Yalen would announce the taking up of arms against the Jedi the next morning, beginning the war.

Opening Days
The Sith, under Darth Yalen, would launch a surprise attack on the Mon Calamari shipyards, where they would succeed in their objective, to a destroy station set up by the Jedi Order. One Jedi survived, and would activate the station's distress signal before perishing. The Jedi learned of the Sith Fleet's next target, Kuat, where their target was, a new Alliance Ship that had recently been gifted to the Jedi Order. They'd arm the ship and place a few ships behind the Shipyard Rings in attempt to hide them. It worked, leading the Sith into a trap, however, the Sith fleet was so large both sides were fought to a standstill, and the battle was ultimately inconclusive, both sides deciding to withdraw. Eventually, the Sith would launch an Attack on Coruscant, where they would almost be successful in reaching the Jedi Temple, but be stopped by a group of Senate Guard who, believing the senators to be in danger, began holding the line by the old senate building. Nonetheless, the Jedi took massive casualties in the attack, and the Sith eventually gained the upper hand. For the rest of the year, setback after setback saw the Jedi forced to retreat to the Core Worlds, and the inner core.

Turning Point
At the beginning of 296 ABY, Yean Talus, a Jedi Master on the council, receives a vision of the former Grandmaster Natalia H'edan. The vision would lead him to go on a search for the source of it, and along the way he'd receive many visions, which would assist him in his search. Eventually, he'd stumble upon a Asteroid Field on the edge of Chiss Space, where a small Abandoned Chiss Cruiser would be sitting nearby. Upon further inspection, he would find a cryostasis pod containing the Former Grandmaster, and wake her. Upon her hearing the news of the war, she'd return to Empress Teta where she'd rally a large group of Jedi on a campaign through the Colonies, and be hugely successful. The reemergence of Natalia H'edan struck a major blow to the Sith, and would bolster Jedi Morale. However, the war was not over yet, and Natalia lead her Jedi forces for almost a year campaigning before being decisively defeated in battle. Her forces destroyed, she'd be forced to retreat, ending the string of Jedi victories and giving the Sith time to mount a counter-attack

End Days
The Ending days of the Great Force War are commonly referred to as the "End War". Thousands of Jedi Died, and hundreds of Sith. While there were less Sith than Jedi, they were arguably more powerful than their counterparts. However, the Jedi were on the Verge of Collapse and it was only made worse by another Sith Attack on the Jedi Temple. This time, Sith diplomats met with the senate guard, and they did not intervene in the battle, allowing the Sith to march into the temple and slaughter them. The remaining Jedi retreated to Empress Teta, where Natalia H'edan had founded her own Jedi Army. Grandmaster Dan Kahalda approved of the army, seeing as its the only thing the Jedi has left to defeat the Sith. Eventually, the Sith reached Empress Teta, however, their forces were also small, and the only thing the Sith had left to really combat the Jedi. They had been whittled down by countless strikes conducted by the Jedi on their way to Teta. Eventually, the two parties met at the Battle of Empress Teta, where the Sith almost won, leaving 21 Jedi left, including Dan Kahalda. Natalia H'edan, seeing the imminent destruction of the Jedi, would board Darth Yalen's ship, killing him in duel and take control of the ship. The remaining jedi, whittled down to 7, would retreat to a nearby moon. The Sith followed them with the last of their forces, which numbered 32. About 12 sympathizers would arrive to assist the Jedi, forcing the Sith to fall back and gather their forces for an attack. As they were doing so, Natalia H'edan told the Jedi to retreat, in which they did, escaping aboard the Sympathizer's ships. A few moments later, Darth Yalen's ship slammed into the Sith forces, killing all but 5, who had stayed behind on Empress Teta. Natalia H'edan died in the process. The Jedi and Sith were forced to agree to peace, both having almost collapsed.

Aftermath
The war killed almost every Sith and Jedi in the galaxy, and would cause a great power vacuum for both the Sith and Galactic Alliance. The remaining Jedi would flee to Natalia, a planet in Firefist named after Natalia H'edan in 267 ABY, where they would live in exile in an old Force Temple in one of the lower levels of the abandoned, overgrown ecumenopolis that dominated the planet. The Sith would also retreat out of the Galaxy, going on a long journey to find a New Galaxy to set up a New Sith Order in. One Sith still remained in a position of power, Darth Tylen, who was the ruler of the Sith Empire. He would realize to focus an empire solely on the Sith Order is a bad model, especially when theres no Sith. He'd soon reform the Sith Empire into the Dark Empire, which would bode well for the former Sith Empire, as without a government that relies on the Sith to be a "Sith Empire", they could function in the absence of the Order. Darth Tylen knew the Sith would return, and his plans were to reform the Sith Empire upon their return. However, both the Alliance and Dark Empire would be unable to achieve much as their enforcers, peacekeepers and some may argue the backbone of their military had suddenly just left them. The end of the Great Force War would leave the Galaxy unbalanced for about 100 years.
