Itonia

The Itonian Peninsula, also referred to as Itonia, is a geographic region is Western Euteria. It borders the Casorian Sea to the northwest, Leppia to the north, Antalia and the Aspean Sea to the east, the Gulf of Ithados to the southeast, the Sea of Amaan to the south, and the Serephanian Sea to the southwest.

Additionally, the island of Casoria lies to the west of the peninsula, the island of Serdica lies to the southwest of Ithados, and the Orillian region of Aspea is separated from Itonia by the Strait of Terrana.

History
The Itonian peninsula was first inhabited by the Etrionans, a Serephanian people. The ancient Delliks established colonies on the southern coast. The first Dellik settlement was on the Corcion peninsula, which they named Ithados. As the colonization intensified, the name grew to encompass all of southern Itonia. A trading economy existed between the Delliks and the Etrionans, with the latter adopting many elements of Eastern Serephanian culture. Several centuries later Sentinate tribes from west of the Capines began migrating into Padonia, settling in northeast Itonia on the Aspean Sea coast.

Around 2300 BCE the Itoso-Leppic-speaking group of Euterians began separating due to the southern expansion of Itosic-speakers into the peninsula. This expansion occurred in several waves over three centuries. The Itons were one of these groups. The Itons migrated into Etrionan territory in central-western Itonia, around the city of Tonum. When the Etrionans were preoccupied and engaged in warfare with the Leppians, the Itons sieged the city and claimed it as their own. They renamed the city as Tona and it became the heart of Iton culture.
