Across the thousands of years of Terragen history, innumerable cultures, polities, and empires have risen, flourished, and passed away. The reasons for their passing are many. Some were conquered by other civilizations, or consumed by Blights or a Perversions. Others ran afoul of some transapient Power and were destroyed for their foolishness. Some fell due to their own internal conflicts or contradictions. Finally, some are regarded as extinct because they have evolved into forms near incomprehensible to their earlier selves.

- Australia - Text by M. Alan Kazlev and Stephen Inniss
An island continent between the Indian and Pacific Oceans on Old Earth. It is the smallest on Old Earth, with an area of 8,560,000 square kilometres, and it was not well suited to long term agricultural uses, so it did not contain any major civilizations or polities until the Industrial Age. After several centuries of sustained immigration, Australia became a prosperous nation, and was an important power on Earth during much of the Interplanetary Age.

Pre-Empires age autonomous Terragen interstellar civilization; many details about it and the reasons for its disappearance remain a mystery.

- Hosoko Hegemony - Text by M. Alan Kazlev
A minor empire in the Deneb volume that had developed following the Great Cygexba Sell-off. In 7254 a local perversity resulted in widespread riots and sabotage; in 7277 the major wormhole links were destroyed and it ceased to exist.
- Hyperion Faction - Text by M. Alan Kazlev
A breakaway faction of the Solar Dominion, dominated by House Marabi Patha and the Hyperion hyperturing, that left after the Information-Emotion Schism in 3414. It turned itself into a competitor to the Dominion by allying with other expansive rimward powers. Part of the Hyperion-Charlwood Alliance.
- Hyperion-Charlwood Alliance - Text by Anders Sandberg
Merger of the Hyperion empire and Charlwood cyborg society, the Alliance embarked on a policy of aggressive military-economic expansion, that culminated with the attack on the strategically important Geteche system. In 3694 the Geteche system was attacked by an unusually virulent form of AI-viruses, developed by the alliance. The attack destroyed the local infrastructure and the governing AI, which led to the explosive destruction of all local wormhole gates. This broke off most of the links between the Orion arm and the young colonies in the Perseus arm. While the viruses were contained in the Orion arm and the perpetrators harshly punished, the remote colonies all succumbed. For several millennia they were isolated, often barbarous and only gradually reconnected to the main wormhole nexus.

- Varadic Hegemony - Text by M. Alan Kazlev
Expansionist Late Consolidation and early Second Federation age biocyborg empire. During the Cygnis Wars both the Varadic and Arantan empires contended for ownership of the most resource rich systems, circumventing the wormhole nexus with relativistic battle fleets, and threatening to attack the stargates if either Cygexba or any of the Inner Sphere powers intervened.
