Tramennis was the sixteenth son of Slately.
Their relationship started roughly, with Slately taking one look at Tramennis' signamancy and immediately sending him to a distant campaign, not caring if Tramennis came back or not.
Afterwards, Slately still had mixed feelings for his son. He appreciated Tramennis' diplomatic skills, but still felt that he didn't fit the Jetstone mold. It took the fall of Spacerock and his own croaking for Slately to embrace his son.
While Tramennis may not have always agreed with his father, he did love him. A word of encouragement would make him beam, and the news that he had croaked and Slately's duplicate would be gone in a Turn devastated him.
