The Diuriabaira (or later "Tirbera") was an apprentice to the order of the Bair. Every Diuriabaira spent four months out of the year under the tutelage of his baira and the other eight traveling far and wide to gather news, carry messages and hunt. It was this constant movement of the Diuriabairas that helped keep the Beiabarnae so closely-knit as a people.
Speculations[]
While Bair seems to stem from gothic baira (*bear), tir seems to be the Anglo-Saxon word tír (fame, glory, honor, *Djurja in proto-germanic). So "Tirbair" could be understood as one bearing honor though more likely originally Honored Bear' was intended, which could be rendered as Diuriabaira in latinized Gothic.
