Aedus/Xerxes

Aedus/Xeres was a Protoss Archon who journeyed to Brontes with the 7th Fleet of Tassadar's Koprulu Expeditionary Force. Arriving at the system, Aedus/Xeres was dispatched to the surface by Judicator Syndrea, along with Demioch and his daughter Edullon, their mission being to erradicate the Zerg that had invaded the planet.

Unlike his fellow commanders, Aedus/Xeres had little to no concept of subtlety, attacking Zerg and Terran forces at will without any direction from Syndrea. Although his actions caused significant damage to the Incubus Brood, it drove the Zerg into a rampage, causing them to slaughter many innocent Terrans in their rampage. Edullon objected to these heavy handed tactics but was branded as a traitor by Syndrea as a result.

Aedus/Xeres was given command of Syndrea's vanguard and attacked Edullon and Demioch's forces, along with the Terrans that had allied with them. However, despite the element of surprise, the vanguard was defeated, with Edullon killing Aedus/Xeres in a hand-to-hand duel.
