The capital of the Realm of Alera, Alera Imperia is the center of the Realm geographically, economically, culturally, academically, and politically. Sitting along the River Gaul and just south of the Redhill Heights, Alera Imperia herself is laid out in concentric rings, with the First Lord's citadel at the very center. The city is home to both the primary political body, the Senate, and the academic center of the Realm, the Academy. In addition, the Grey Tower also was built in Alera Imperia—a reminder that no one is above the law. Its colours are Scarlet and Azure, the colours of the House of Gaius and the First Lord.

Alera Imperia stood for hundreds of years as the center of the Realm, until it was consumed in the Vord War. Gaius Sextus evacuated the city and sacrificed himself to rouse the great fire fury beneath the city. The city was destroyed along with the majority of the vord host, and the aftermath lit the sky for 50 miles around.
