Change

Apart from the sixteen Technic History instalments about the Polesotechnic League and the fifteen about the Flandry period, the remaining twelve instalments convey times of change. 

In "The Saturn Game," exploration of the Solar System has begun and Earth is being renewed after the Chaos.

In "Wings of Victory," the first interstellar Grand Survey has begun and Ythri is discovered.

In "The Problem of Pain," Ythrians have become spacefarers. Some have studied on Aeneas and are now exploring Avalon.

"Wingless" and "Rescue on Avalon" are about the early stages of the colonization of Avalon.

"The Star Plunderer" is about the Time of Troubles and the proclamation of the Terran Empire.

"Sargasso of Lost Starships": the early Terran Empire has just incorporated Ansa.

The People of the Wind: The Terran Empire and the Domain of Ythri adjust their borders while the Merseian Roidhunate grows.

"A Tragedy of Errors": alliances are formed during the Long Night.

"The Night Face": a long isolated planet is re-contacted.

"The Sharing of Flesh": the Allied Planets re-civilize isolated planets.

"Starfog": humanity has spread through several spiral arms, the planet Vixen, which existed in the Flandry period, has established its own colony, appropriately called New Vixen, and a new era of immense wealth is about to begin.

"'Every end,' Wagoner wrote on the wall of his cell on the last day, ' is a new beginning."

Posting about the end of Anderson's Technic History recalled the end of Volume I of Blish's future history.
