Galactium

The Galactium is the term given for the area of the galaxy directly affected by astropolitical entities. The term can also refer to the area of the galaxy that was under direct jurisdiction of the Ecological Galactic Republic before its fall in the 39th century.
The term has origins in the early colonisation of space in the 26th and 27th centuries, with speeches from notable figures such as Caiiper and Thodereon promising to bring forth a united galactium under rule by Earth. When it became clear that the colonisation of the galaxy had come to a standstill, the term shifted to describe the extent of the EGR proper.
