- The Tales of the Jedi comics happen. After the end of the comics, there are several millennia of peace and prosperity in the Republic, until 2000 BBY.
- In 2000 BBY the Mandalorian Wars take place. The reasons of why the Mandalorian Wars happen are the same reasons of why they happened in the original Knights of the Old Republic lore, before The Old Republic MMO retconned everything. The major events of the Mandalorian Wars are the same that are described in the Knights of the Old Republic comics. However, Cassus Fett is replaced with a new character, as my Old Republic head-canon (just like my Prequel rewrite) respects Boba Fett’s pre-Prequel backstory, and so the Fett family doesn’t exist as such.
- After the end of the Mandalorian Wars, Revan and Malak fall to the Dark Side, revive the Sith cult and unleash the Jedi Civil War. The following events are similar to those described in the first Knights of the Old Republic game. However, the Jedi are more similar to the Jedi from the Tales of the Jedi comics, and look nothing like the Jedi from Lucas’ Prequels. Apart from this, Revan and Malak’s story is similar to what’s depicted in the first KOTOR. So, we still have Bastila and the other characters, Malak is still defeated, Revan is still redeemed, etc.
- After Revan’s redemption, the Republic continues to fight against the remnants of the New Sith Empire founded by Revan. The war goes on until 1000 BBY, when the Sith are definitively defeated in the Battle of Russan. However, a Sith survived the battle, and this Sith is Bane. So, after the defeat of the old Sith, Bane created the Rule of Two, established the use of the Darth title (which didn’t exist before him) and also established the red lightsaber rule for the Sith.
Since I have completely abandoned my plans to rewrite the Prequel Trilogy and the Old Republic, this head-canon must be changed.
I currently accept the Old Republic Era the way it’s portrayed in the already established EU timeline. However, I keep the changes regarding the Darth title and red lightsabers. So, every Sith prior to Darth Bane never used the Darth title, and there wasn’t the rule to use a red lightsaber. Both these things were created by Darth Bane itself. That is, everything happened in the same way as in the already established EU timeline, but the historical archives of the Galactic Alliance contain some small inaccuracies. Therefore, what’s depicted in KOTOR/SWTOR is extremely accurate and reflects what really happened, except for the Sith aesthetics. Due to this small inaccuracies, the galactic historians use the Darth title to describe the pre-Banite Sith an depict them as using red lightsabers, when they actually looked more like the Sith from the Tales of the Jedi comics. This explains why in the KOTOR games, in SWTOR and in their tie-in material we see the Sith looking like the Sith from the PT, when they actually didn’t look like that. In the real universe the Sith look from the Prequels was born with Bane and died with Sidious, after which there were no more Sith (as my head-canon universe ends with the NJO series anyway).
