In the twenty fourth, twentieth and nineteenth centuries, Time Patrol colleagues discuss Carl Farness' fourth century experiences with him. These three very different colleagues include Unattached agent Manse Everard. Thus, we do not lose touch with the original central character of the series although we also meanwhile receive a much broader perspective on the Patrol.
In 337, Dagobert falls in battle against the Huns.
In 1933, Laurie comforts Carl.
337-344, another section summarizing changes in the world, ends with Tharasmund married to the Visigoth King Athanaric's daughter, Ulrica. Constantine divides the Empire East and West, makes Byzantium, renamed Constantinople, the Eastern capital and declares Christ the single god of the state. (Later: see comments.) Many West Goths are converted although not yet the Ostrogoths who include Tharasmund's Teurings.
337-344, like the earlier 302-334, has a collective point of view. We are told not what Dagobert or Tharasmund thought but what others thought of them:
"Dagobert stayed unrestful, though; folk said that was the blood of his father in him, and that he heard the wind at the edge of the world forever calling." (Time Patrol, pp. 382-383)
(Their world indeed has an edge but they have no conception of what lies beyond it.)
"The restfulness of [Tharasmund's] line was in him too, and he wanted freedom to travel.
"That was well for in those days many changes passed through the world. A chieftain must know them before he could hope to deal with them." (p. 396)
(Change, even for those who can travel through time, is the constant theme of the series.)
