Terran Defence Organization Bases

Across its history, the Terran Defence Organization built or used a variety of bases, which are listed here.

Hispania Base
Hispania Base was built in 1 B.T., initially as a temporary base for the Human Resistance in their war against the Vortex. After the Second Battle for Earth, it became the main TDO base in the Interregnum until the construction of Terra Base.

It was home to a Singularity Tower, the only one in the Interregnum, and would be home to most interdimensional research and E-99 projects, until the latter were passed over to Base Katorga.
