21 BBY, July 4.
Galactic Republic Capital Coruscant, Jedi Temple top floor, Jedi Order High Council chamber.
"...That is what happened, Master Yoda. Archangel of Death personally admitted that his other identity was Tang Xiao, Governor of Dawn Star Planet. He also told us that the other Sith Lord, Darth Sidious, was Chancellor of the Galactic Senate Sheev Palpatine himself," Master Windu said gravely.
Only the three of them were in the chamber now: himself, Master Yoda, and Obi-Wan Kenobi, who had been directly involved.
"Hmm... the Rule of Two, the tradition of the Sith Lords. That means there are two master-apprentice pairs in this Milky Way Galaxy." Master Yoda leaned on his cane, unable to conceal the exhaustion and weariness on his face. Yet he still forced himself to focus, to think, to feel.
"That's right. According to Archangel of Death, he and Edra Kestis, who was also Darth Lilim, were one pair of Sith master and apprentice. Darth Sidious and Count Dooku, leader of the Separatists, were the other pair. Count Dooku's Sith title was Darth Tyranus, but according to Archangel of Death, he had not recorded Count Dooku in the Book of Sith. Strictly speaking, Count Dooku could not yet be considered a Sith," Obi-Wan Kenobi said.
"Hmph!" Master Windu snorted. "Those scum lurking in the shadows certainly have no shortage of underhanded tricks and bizarre so-called traditions!"
"A catastrophic disaster, for the Jedi Order and the Galactic Republic, if what Archangel of Death said is true." Leaning on his cane, Master Yoda walked to the window. "The power of the Dark Side, always shrouding the core of the Milky Way Galaxy. Archangel of Death's intelligence revealed why."
"Master Yoda, are you simply choosing to believe intelligence from Archangel of Death when he is so obviously ill-intentioned?"
