Scion

Scion was a province of Aiur which fell to the Zerg in the early stages of their invasion of the planet. Most of the province consisted of elevated land, featuring a basin in its western area. Northeast however, the elevated land gave way to lower jungle, featuring a Protoss settlement/fortress.

Reclamation
"Executor, we shall lead our main strike force to the province of Scion which has fallen to the Zerg. It's time the Zerg felt the wrath of the Sons of Aiur!"

- Aldaris

The reclamation of Scion could be said to be driven by pride more than anything else. After a attack on a Zerg cerebrate, Judicator Aldaris declared that the Zerg will be overwhelmed with the might and the fury that is our heritage!; possibly a reflection of the will of the Conclave. Scion would serve as an example of Protoss might.

With Praetor Fenix maintaining a small force at Antioch in case of counterattack, the Executor led his forces against the Zerg forces there. The Zerg controlled most of the province, the Tiamat Brood stationed in the basin and the Baelrog Brood stationed in the province's main settlement. Nevertheless, the Protoss were able to reclaim the province for the Firstborn.
