Herdr'tui was a male Stereb, who lived on Prakith in the years following the formation of the Galactic Empire.


Herdr'tui was among a group of Stereb who lived in the underground caverns of Prakith and he was the keeper of a greethka, a type of dangerous creature. After the Imperials sealed off some tunnels, he became stranded on the planet's surface, in the Work Zone sector of Prak City. He encountered a group of Alderaanian Resistance agents and with their help, he was able to return to the underground Stereb caverns via a series of tunnels known as The Drains.
