The Cosmos Future History

If Poul Anderson's Psychotechnic History were to be collected in two volumes, Volume I beginning with "Marius" and ending with "Brake," Volume II beginning with "Gypsy" and ending with "The Chapter Ends," would a reader think that they were a single future history or two independent ones?

In "Teucan":

Weber's full name is Weber Franz, i.e., surname first, personal name second;

he swears by Cosmos;

the text refers to the Coordination Service, to a Galaxy too big to be controlled and to an earlier Second Dark Age -

- but there is no reference to any events between the readers' present and that Second Dark Age.

The Cosmos future history could be autonomous.
