Dawgu Island

Dawgu Island is 167 kilometers south of mainland Vircazihm in the Osamian Ocean. It is approximately 70 km across east to west and approximately 50 km across north to south.

Geologically, it began as an volcanic island on the Tefftan Plate and is quite old. Relatively recently in geologic history, it accreted from the Tefftan Plate onto the Giradaw Plate at the Akoshu Subduction Zone (ASZ). It is made up of very old basalt, older than the Ṇepå Mountains of Vircazihm and this is mixed with blocks of sedimentary rock originally formed on the seafloor of the Tefftan Plate.

The island was first settled by proto Ulete during the bronze age. Tefftan occupied the island during the Middle Ages and they used it as a base for trading and raiding. The Kingdom of Vircazihm took control in the late Middle Ages until it was contested by Agarad in the 18th Century, exchanging hands several times until Ordrey, at Vircazihm's invitation in and act of Realpolitik, took the island in the 19th century and created a trading post there. It returned to Vircazihmese control in 1944 after the defeat of the Ordrish occupation forces in Vircazihm.

It is unique linguistically. The primary language of the native islanders is an old dialect of Tefftanic that branched from Old Tefftanic in the Middle Ages. It is spoken nowhere else. Ulete and Amorese are also increasingly spoken.
