Constructed in 2132, Earthdome housed the Office of the President of the Earth Alliance, the Earth Senate, Earthforce Command and, until its dissolution, Psi Corps Headquarters. Other ancillary functions, such as xenobiological and weapons research, have significant facilities within Earthdome as well as several major alien embassies. From an architectural standpoint, the complex is designed with a golden reflective roof, which shimmers in the sunlight and can be seen from orbit when there is no cloud cover.
