Orillia

Orillia is a subregion of Central Euteria. It borders the Aspean Sea to the west, Palladia to the northwest, Thydia to the northeast, the Azal Sea to the east, the Sargonian Sea to the south, and the Sea of Amaan to the southwest. Traditionally Orillia was divided into the regions of Aspea, Pythea, Dellos, Nysiae, Pelaseia, Massidea, and Magnessa.

Orillia has been inhabited by a variety of different groups throughout history; Serephanians, Sargonians, Indigenous Orillian groups, Itosian peoples, Aspeans, Leppians, Tonans, Oranic peoples, and Bergaric peoples, among others.

Pre-Antiquity
The first people to settle the region were small numbers of the Hiberian Hunter-Gatherers. The first large-scale settlement was done by the Serephanians, an Iseret group, who originated in Ancotania. Next were the Sargonians, who colonized southern Dellos and various Orillian islands from the island of Sargon, off the coast of Numeria. The first Euterian branch to migrate to the region were the Ancotanians, who settled in Theron, Acropolis, and Magnessa. The next Euterian colonization came from the northeast, signalling the arrival of the Proto-Orillians.

Regions
Historic regions of Orillia include Dellos, Pythea, Massidea, Nysiae, Pelaseia, Aspea, Picedonia, and Chomaria.
