People who understand this are considered to be quite advanced prequel players.
Palpatine, who founded the Empire and proclaimed himself Emperor, explains the Jedi conspiracy in the Imperial Senate.
Explain to the nation how the Jedi plotted for years and executed a disastrous war plan.
There he can use useful tools. This is Mechno chair.
As Lord Sidious, all of his conversations with Count Dooku, Nute Gunray, Grievous, and others are recorded. It's the fruit of cunning.
The public doesn't know that Sidious is Palpatine. The Emperor does not reveal.
If you explain that the Jedi was talking to Count Dooku as Sidious, it makes perfect sense.
It demonstrates a scenario where Count Dooku and the Jedi Council were manipulating the war, rather than Sidious and Tyranus manipulating it behind the scenes.
That's why, instead of destroying the Crafty Crystal Mekno Chair, I carefully preserved it.
The people who hear Sidious' audio recordings become angry. The Republic's valuable secrets and information were being passed on to the Separatists. I can't forgive it. He purposefully caused the Republic Army's numerous operations to fail.
We can see how the Jedi were cleverly deceiving democracy.
(There is no problem in theory even if the audio recording itself is not tampered with.)
It's a galaxy without Jedi, so we can't prove it's a lie.
Mechno chair has great historical value.
Count Dooku was called "Tyranus" and Sidious, and the Jedi were wary of their conversations being intercepted. Unlike Sidious, Dooku does not change his voice.
By the way, the Emperor also obtains the recorded data inside the Jedi Temple.
This cannot be published.
(Let's say that Mechnochea was discovered and seized in the Jedi Temple. It would be better to pretend that it was discovered through the Empire's intelligence agency, rather than the Emperor.)
"I was deceived by a Jedi and I was terrified at that time."
During the war, he secretly contacted several senators as Sidious.
It turns out that they are actually Jedi. You can bury Palpatine's evil plans.
*During the war, Gunray's Mechnochea once fell into the hands of the Republic Army. The Jedi investigated and reported to Palpatine. Since the Jedi were involved, I didn't make it public at the time.
*Isn't Lord Sidious a Jedi? This is something Gunray thought about a long time ago.
He learns that Sith Lords secretly exist and becomes frightened.
