The Galantos Guard was the primary naval defense force of the Fia species and their homeworld of Galantos. It was originally created to protect Galantos against the Yevetha during the Black Fleet Crisis from 16 ABY–17 ABY.
During the Yuuzhan Vong War, in exchange for what the Galantos believed to be protection from the extragalactic invaders, they informed the Yuuzhan Vong of the brutal Yevetha and the threat they might pose. Taking heed, the Yuuzhan Vong invaded the N'zoth system.
The details of the battle may never be known, but if the Yevethan and Yuuzhan Vong tactics say anything, the Yuuzhan Vong destroyed every single ship in the system, and unleashed a horrible orbital bombardment on N'zoth that rendered the planet a molten wasteland. At the end of the conflict the Yevetha were either extinct or severely endangered.
