Pererria is a Territory of the Empire of Adammia, surrounded by the West Midlands in the United Kingdom. It is made up of a section of quayside and the adjoining canal. It is most notable for being home to the headquarters of the Adammic Navy, Pererria Naval Base. It is 157m² in size. Its governor is Admiral Emily Simpson.

Pererria was originally located in Poole Harbour, but was forced to move after the bar adjoining the territory, which was previously owned by relatives of Admiral Simpson, was sold to persons unknown. It is now located near to Simpson's term-time workplace.
