Brudick is Lakarthe's elder brother. Rvials for the affections of Zita, they constantly bickered as children. The rivalry was not settled when Lakarthe was chosen as Zita's successor to the Guild, and they've been bitter rivals ever since.
Lakarthe is Brudick's younger sister. They were both fond of their half-sister Zita and were constantly fighting for her affections. Brudick was livid when Zita chose Lakarthe to lead the Leviathan Hunting Guild over him and sought to take the right away from Lakarthe by any means.
