Primoria is a county of the Empire of Adammia located in the province of Greater Tytannia. It is 218m² in size and has a permanent population of 3. It is made up of a semi-detached house, two gardens and a garage. Primoria was the Empire's oldest Province during the First Era before being downgraded to a county by the Empire of Adammia Act 2017. It is also notable for being where the Imperial Family resides. Originally it was known as the Adammic Imperial Province, but it was renamed by the Legislative Amendments Act on 22 December 2013.

Primoria has an open border with the UK facing south-west. This border is where Belcher Street begins as it makes its way past a small green area known as the Imperial Plains before reaching the city of Adamsville, where the government offices mentioned above can be found in 1 Belcher Street, also known as the Imperial Household. Behind the residence of the Imperial Family is Adamsville Park, which marks the back of Adamsville, leading on to a few extra metres known as the Jebediah Hills (named after the patron saint of Adammia) before reaching the opposite Adammia-UK border.
