Sarkkin was a male Wookiee explorer active by the time the Yuuzhan Vong War broke out in 25 ABY. Partnered with Panha, Sarkkin and his companion explored the edge of the galaxy aboard their starship the Pythea, acting as the vessel's only crewmembers. When, in the first months of the year, Sarkkin received a transmission from an unknown source, he and Panha were surprised to discover a warning from an individual of a race brought almost to extinction by the invasion of a powerful species known as the Yuuzhan Vong. The two explorers discovered that they were in the path of an approaching Yuuzhan Vong fleet and together they rushed to the nearby world of Artorias in order to warn the inhabitants of the planet of the threat they faced.
