His family include; his parents Tiss and Trilli, his uncle Till, Trill and Vissi his aunts, and Ziss and Trinn who are his cousins.
In his spare time, Tryss made a harness which helps to injure animals, and be used for attack and defense. He tested it out to show others, and ended up gaining the help of Drilli who added a blowpipe to the contraption. He then showed the harness out to the entire group of Siyee, who realised the potential in the device.

Tryss' harness ultimately led the Siyee to go to war, and he helped teach Siyee warriors how to make and use the harness in battle. Before heading to war, Tryss married Drilli with Sreil's help. With that, he moved out of his parents bower and shared one with Drilli.
During war, Tryss joined in the war dicussions and was assigned a Siyee squad. However, at the end, he was the only survivor from his team. He saw an opportunity to attack a Pentadrian Voice when Imenja was focused on attacking the White. He threw a dart at her using the blowpipe which hit, but she recovered and retaliated. Tryss ended up horrifically mangled and nearly died, but Leiard heals him, and he find out Drilli is pregnant.
