In "When the Tide Rises" (pg 13), Rene Cazelet tells Adele at her home that his father & mother "were arrested on Pleasaunce by agents of the Fifth Bureau. They were charged with conduct prejudicial to the good order of the state, which is treason under the War Emergency Powers proclaimed by Gaurantor Porra. Their trial was of course secret, but it seems a foregone conclusion that they were executed."
“I wasn’t arrested at the time,” Cazelet, continued, “because I was with my grandmother. (On Bryce) I was studying information storage and retrieveal techniques to help me in my duties for Pheonix Starfreight, the shipping line which my father owned. We had twelve vessels, though—again, of course—they’ll have been confiscated by the State under the treason regulations.”
