North American Union And Diamond Dust

Twilight World And Maurai informs us that:

"In Twilight World, the remnants of the United States and Canada merge as the North American Union..."

Both Rapid Technological Advances And Geopolitics and Alaric Wayne II refer to that same North American Union.

In North American Future History, the US and Canada amalgamate as the North American Federation.

In The Maurai Period, there is a North West Union.

In Pun And Gun, a North American Intelligence officer interrogates a rebel asterite.

In Robert Heinlein's The Star Beast, the North American Union is one part of Earth which is the leading planet in the Federated Community of Civilizations, usually referred to as the Federation.

Again, we find terminologies common to different fictional futures.

While searching for the North America in Tales Of The Flying Mountains, we find yet another description of the Milky Way:

"...the Milky Way girdled the universe with diamond dust..."

-Poul Anderson, Tales Of The Flying Mountains (New York, 1984), p. 104.
