Khalai Revolt of Shakuras (The Insurgent)

The Khalai Revolt of Shakuras was a attempt by Judicator Aldaris to overthrow the Dark Templar, seeing the alliance between protoss and Infested Kerrigan's zerg as a defilement of Aiur's memory. He was also secretly aware of Kerrigan's manipulation of the Dark Templar matriarch, Raszagal.

History
When Artanis and Zeratul returned to Shakuras, they found it in the throes of a revolt. Aldaris took control of an entire legion of protoss refugees, including virtually all of the Templar and Judicators, and led them in an attack against Raszagal. The Matriarch returned the favor.

Raszagal: "Executor, as Matriarch of the Dark Templar and custodian of this world, I hereby order you to terminate Judicator Aldaris, and quell this untimely uprising without delay! There will be no dissent among us while the Zerg are poised to strike!"

However, Zeratul had known Raszagal for a long time and felt that, perhaps, Aldaris was on to something. Out of Raszagal's earshot, he said to Artanis:

"There is something amiss here. The Matriarch has always been a wise and gentle soul. Though there is some merit in her decision, this is very unlike her."

Nonetheless, the Matriarch's forces attacked. Raszagal had even authorized the creation of the dark archon, something which had not been done for a thousand years (about the time the Dark Templar were exiled from Aiur). Using the dark archons' ability to control the minds of their foes, she was able to defeat Aldaris' revolt.

Artanis and Zeratul confronted Aldaris, who claimed that while these two protoss were away, he discovered that Raszagal was harboring a dark secret; she was being manipulated by Kerrigan. Kerrigan interrupted his explanation by murdering him.

An infuriated Zeratul immediately banished Kerrigan, who retorted "Fine. I've done what I came here to do. I've insured the destruction of the renegade Cerebrates, and I used you to do it. Have fun, mighty Protoss... We'll be seeing each other again, real soon..."
