Aldaris

Aldaris is a 740-year-old powerful Protoss Judicator in the service of the Protoss Conclave. He was a stalwart supporter of the Khala. An agent of the Conclave, he served as Overseer to the Expedition fleet under Tassadar. He had a strong hatred of the Dark Templar, and would not hesitate to label those who disagree with his philosophy as heretics.

In StarCraft and Brood War, Aldaris is voiced by Paul Eiding.

We first see Aldaris in-game as an advisor to the new Executor at the beginning of Episode III, after the Zerg Overmind landed on Aiur and its Zerg troops rampaged over the planet, winning a string of victories.

Aldaris helped direct a nearly hopeless battle in the province of Antioch, and seeing Fenix achieve victory there, announced that he had regained faith in the Templar Caste. Tassadar appears, telling Aldaris that he should never have lost faith. Aldaris tells Tassadar to return to Aiur, but Tassadar refuses. "He has learned much from the Dark Templar Prelate Zeratul," he says, and Aldaris calls this heresy. He claims to sense the taint of the "Fallen Ones" on Tassadar's mind.

Over Aldaris' objections, Fenix follows Tassadar's proposed plan - to kill a Zerg Cerebrate and thus greatly weaken it's Brood. The plot was not a success, as the Cerebrate reincarnated. Aldaris believed Tassadar tricked them.

Aldaris directs the next Protoss assault - into the province of Scion. He orders Fenix to maintain his outpost in Antioch with a small number of warriors. While the Zerg in Scion are defeated, so is Fenix ... when Fenix calls for help, Aldaris told him to hold out as long as he could.

Shadow Hunting
Believing their strategy is working, Aldaris travels to Char in order to hunt down Tassadar. While Tassadar told him that the Zerg were no longer on Char, it seems he was wrong. Aldaris was able to sense their presence at quite a distance.

Fighting their way past the Zerg, Aldaris' small escort encounter Tassadar and Jim Raynor. Aldaris proceeded to insult Tassadar for his choice of companionship, while Tassadar is outraged that Aldaris would come all the way to Char to arrest him, rather than fight the Zerg on Aiur.

Aldaris accuses Tassadar of lying about the Cerebrate, but Tassadar reveals that a Cerebrate can only be killed by Dark Templar energies.

Tassadar convinces the new Executor to follow him, despite Aldaris' attempts to keep him on his side.

The Fall
Tassadar and Zeratul, along with a band of Dark Templar, arrive on Aiur, with a plan to defeat the Zerg. However, the Protoss Conclave stands in their way.

With the assistance of the injured Fenix, who now inhabits a Dragoon exoskeleton, Tassadar's forces destroyed the Heart of the Conclave. Zeratul's stealthy tactics were key to this victory.

After the battle, Tassadar declared that he couldn't handle killing his own people anymore and surrendered himself. Aldaris then appeared in a Carrier and took Tassadar into custody. Tassadar was imprisoned in a Stasis Cell while put on trial for his life. Meanwhile, Zeratul and his Dark Templar had vanished.

Believing the trial to be unfair and biased, Fenix and Jim Raynor launched an effort to free Tassadar. While successful, Aldaris appeared in a Carrier again, ambushing Tassadar and his allies. He was, in turn, surprised by Zeratul and his Dark Templar.

Aldaris and Zeratul traded insults (with Zeratul getting the upper hand) and the two forces battled. Zeratul came out the winner.

Eye of the Storm
Zeratul led an attack against two Zerg Cerebrates on Aiur, slaying them both. As he and his allies prepared their assault on the Zerg Overmind, Aldaris communicates with them, saying he is sorry. His forces had observed the death of the two Cerebrates and the effects these deaths had on the Zerg.

Unfortunately, the apology came too late to offer troops or other material aid to Tassadar and Zeratul, earning the scorn of Jim Raynor.

The Stand
Aldaris became a leader of the Protoss even after the death of Tassadar, although this forced him to ally with the Dark Templar Prelate, Zeratul. He travelled to Shakuras and became estranged by Matriarch Raszagal after she welcomed Kerrigan as an ally.

While Kerrigan, Artanis, and Zeratul searched for the Uraj and Khalis crystals, Aldaris discovered that Kerrigan had somehow corrupted the Matriarch's mind. By the time Artanis and Zeratul returned, he was leading a full-scale revolt. The Matriarch ordered the Dark Templar to attack his forces, even allowing the creation of Dark Archons for the first time in a thousand years. Zeratul began to wonder if something was wrong with her.

Despite Aldaris' clever use of illusions, his forces were defeated. He revealed his reasoning to Zeratul and Artanis just as Infested Kerrigan arrived and killed him.

Kerrigan was banished from Shakuras for her interference, but would later return.

Meanwhile, the death of Aldaris meant that no one could discern that Matriarch Raszagal was still being corrupted by Infested Kerrigan. This would have disastrous results for Zeratul and the Protoss in Episode VI.
