The Presence settles on Malachor V to create a Sith Temple there. She is later joined by other Sith.
The Presence creates a petrification superweapon in the temple, which is to be powered by her holocron, which contains a kyber crystal to power both the holocron and the superweapon. It is not the Mass Shadow Generator, and there is no indication that Revan ordered Bao-Dur to create it to massacre the Mandalorians to end the Mandalorian Wars. There is no indication that Revan, Meetra, Bao-Dur, or Mandalorians were involved.
The Jedi Order finds out about the Malachor superweapon, but in the battle, the Presence activates the weapon, petrifying everyone in the vicinity.
Before 1032 BBY
The Great Galactic War (possibly the same as the New Sith Wars/the Jedi-Sith war?) between the Old Republic and the Sith Empire seems to come to a diplomatic end on Alderaan... while actually meeting an end with a surprise attack on the capital world, in an event deemed the Sacking of Coruscant.
Shae Vizsla deactivates the defense grid of Coruscant, allowing Darth Malgus and his men to attack the surface of Coruscant and the Jedi Temple. Supreme Chancellor Berooken, many high-ranking Jedi, and civilians are killed, and the Temple is reduced to rubble. Coruscant is locked down by the Sith and held as a hostage for the negotiations on Alderaan for two days.
After the Jedi Temple is massacred, Shae Vizsla takes the Darksaber from the Jedi Temple on Coruscant before leaving.
The Republic is forced to agree to the Treaty of Coruscant. The Sith Empire annexs almost two-thirds of the known galaxy. The Cold War begins.
The Jedi return to Tython, and Sith Emperor Vitiate puts his Dark Council in charge of everyday tasks for the Empire. The Sith are in control of Coruscant.
After about a decade since the Treaty was signed, the Treaty is broken.
At some point, the Liberation of Coruscant is carried out by the Jedi/Old Republic, freeing the world from Imperial occupation and turning the tide of the galaxy once again.

Commander Fox kills Fives before he can explain the chip to Anakin & Rex. The conspiracy is covered up as an isolated incident regarding a parasite shared between Fives and Tup when they shared water canisters.
