After retrieving the Uraj and Khalis, Dark Prelate Zeratul, Praetor Artanis, the Executor and Sarah Kerrigan returned to Shakuras to find the protoss in a state of civil war. Matriarch Raszagal informed them that Judicator Aldaris had taken command of a number of Khalai Refugees and was leading an insurgence, and claimed the reasons he was doing so were because he thought abandoning Aiur and siding with the dark templar was wrong. Raszagal ordered the Executor to quell the uprising and kill Aldaris, refusing to tolerate dissension as the protoss prepared to move against the zerg. Zeratul was disturbed by Raszagal's violent response to Aldaris' actions, considering her a gentle soul.
The protoss reached the battlefield where Aldaris had established his forces. Most of the high templar had sided with him, and their arbiters seized as well. Artanis feared Aldaris would resort to sending archons against them. In response to the threat of archons, the dark templar authorized the creation of their most powerful weapons - dark archons, long outlawed due to their tremendous and unstable power.
With the dark archons aiding them, the protoss pushed their attack to Aldaris' base. They discovered that Aldaris had created illusory copies of him and spread them over his forces as distractions, and mocked their gullibility in falling for the deception. Eventually they cornered the real Aldaris, and Artanis and Zeratul parleyed with him, asking Aldaris to stand down. Aldaris refused, declaring that the alliance with Kerrigan would see the protoss made into her slaves. Artanis assured Aldaris Kerrigan had reformed, but Aldaris said he was naive, and he had learned a dark secret about Raszagal.
