Eureka (Tipsprek: , tr. Jureeka), officially known as the Realm Viceroyalty of Eureka (Tipsprek: , tr. Rykfisekeizereklye fan Jureeka), is a Realm Viceroyalty and dependent territory of the Holy Tiperyn Realm. The viceroyalty includes both the territory of Eureka on the continent of Hyberia as well as nearby Tulp, Van Noort, Van Eyck and Vesalius Island groups in the Hyberian Ocean.
Eureka's population consists of 26,500 permanent residents as of 2019 as well as 9,000 to 12,000 transient military personnel. Its capital of Point Eureka is the largest permanent human settlement both on Hyberia and south of 45°S. Further, Naval Air Station Eureka located on the outskirts of Point Eureka is the Tiperyn Realm Defence's largest single overseas military base, although other dependencies and territories have a larger total number of military personnel. With an area of 105,725 km2 (40,821 sq mi), Eureka has a population density of 0.3 people per km2 (0.8 per sq mi) although this does not include military personnel who live on Naval Air Station Eureka.
First recorded human settlement dates back to the Tiperyn landings at Point Eureka—also the northernmost part of Hyberia—in 1809. However, the archaeological record indicates that Native Avalonians inhabited the islands as far back as back as 30,000 years ago. These early settlers likely sailed from what is now southern Kaya or SiWallqanqa and settled the long chain of islands in the South Tethys Ocean and Hyberian Ocean before making landfall on Hyberia. No living humans were discovered by Tiperyn settlers, however.
