Cynan And Psychotechnics

Cynan's confession here was an unexpected link to Poul Anderson's Psychotechnic History. In that future history series:

After World War III, the UN struggles heroically to rebuild society and to prevent further war while the Psychotechnic Institute struggles heroically for social and individual sanity. The UN becomes the Solar Union. The Institute fails to prevent social chaos and is overthrown although organizations like the Planetary Engineers continue to employ psychotechnicians. Society declines into the Second Dark Ages.

The hyperdrive is invented. In the Stellar Union period, planetary civilizations are either integrate or unintegrate. Nomads with some recruits from the Coordination Service preserve knowledge through the Third Dark Ages. In the Galactic period, psychotechnicians have gained superhuman psychophysical powers.
