Development of the Terro-human Future History

"I don't know what plans you have for a next story project, but the world-picture you've been building up in the Sword Worlds stories, or Space Viking stories, or whatever you designate the series, offers some lovely possibilities."
— John W. Campbell (to H. Beam Piper)

Terro-human Future History Development Claims

"Should we do more exploring and claim some more of these places, or should we come home right away and start recruiting, and then come back with a large party . . . and explore and make further claims as we have time?"
— Conn Maxwell (H. Beam Piper), The Cosmic Computer

Modeled after the Traveller Mailing List (TML) Landgrab, Piper Development Claims are personal, non-commercial efforts to develop the worlds and future history of H. Beam Piper's fictional Terro-human Future History.  Each background developer should report on the claimed world (or future historical century) in great detail.  The exact level of detail and degree of compliance with official canon is open to interpretation.  Each background developer should survey his or her claim (including gathering the relevant canonical information) and submit a Developer's Report to the Piper Mailing List.

A key guideline for any development effort is captured in "Newton's Rule":

"Perhaps, in keeping with the spirit of the Landgrab, and so that we can both stimulate creativity and remain careful about what Piper actually wrote, we should separate material into "Canon" and "Apocrypha"--with the latter segments being so titled to represent the fact that the author is not revealing but extending. . . ."

The claims made thus far include:

World Claim


Date of Claim


William Taylor

July 2001


David Johnson

Poictesme (now The Tides of Chaos)

Dietmar Wehr

October 2008

In addition to development claims to the worlds of Piper's Terro-human Future History others have expressed an interest in developing specific centuries of the TFH "Atomic Era."  Here are those claims:

Atomic Era Century Claim


Date of Claim

First Century, AE

Steve Newton

August 2001

Second Century, AE

David Johnson

Tenth Century, AE (now The Tides of Chaos)

Dietmar Wehr

At the suggestion of Piper fan Tom Rogers, Piper Development Claims have been expanded to encompass the process of comparing various editions of Piper's work for consistency and differences in order to expand and clarify the canonical material used for development.  Developers in this area choose a given work and report on their comparison of the various editions.  The claims made so far include:

Canon Claim


Date of Claim

Uller Uprising/"Ullr Uprising"

Tom Rogers

September 2001

"Oomphel in the Sky"

Tom Rogers

January 2002

If you wish to participate, stake your cliam on the Piper Mailing List.  If none oppose you, or if you prevail in an ensuing discussion, you too may become a background developer.

Background developers may lay their claim and/or provide links to their Developer's Report by posting an announcement to the Piper Mailing List.  Developers may have their Developer's Report hosted at here by sending a request to the Development Claims Bureau.
