Histria

The Histrian Peninsula, also known as Histria, is a region of Central Euteria that juts out into the Aspean Sea. Geographically the peninsula separates the Palladian Sea in the east from the Bay of Histria in the west.

The Histrian Peninsula was first inhabited by the Histrians, who belonged to the Aspic family and were related to the nearby Palladians, Cambrians, Aspeans, and Aesonians.

Early history
The Histrian Peninsula was sparsely inhabited before the arrival of the Euterians. Most of the population was centered on the west coast, which was home to Sargonian colonies.

The Euterian Expansion brought the Aspic people to the region. Proto-Dello-Aspic speakers most likely arrived in the area north of the Palladian Sea before separating into Aspic and Dello-Corian groups. The Aspic-speakers resided in southern Cambria and broke into three subgroups. The original Cambrians remained behind while the other two began migrating throughout the Aspean Sea. The western branch, comprising the Histrians and the Aesonians, migrated west into Histria and southern Itonia. The other group, the eastern branch comprised of the Palladians and Aspeans, migrated into Orillia.

The Delliks founded colonies along the coast of the peninsula. They interacted with the native Histrians and produced a Dello-Histrian cultural exchange. The most prominent of these Dello-Histrian cities was Sarconian at the southern tip of the peninsula.

Tonan province
Histria was a region and province of the Tonan Empire, located on the Histrian Peninsula in central Euteria. The province shares one land border with the region of Cambria to the north, alongside maritime borders with Itonia to the west, Samaria to the east, and Orillia to the southeast. Histria was one of the most important parts of the empire owing to its proximity to Itonia and the northern trading routes.
