Rohak, a Human of the male gender, was among the original founders of Aurilia, a village situated on the planet of Dathomir. In time, he ascended to the role of village elder and also served as its spiritual leader. During the era of the Galactic Civil War, he was a very aged and insightful Human, and it's documented that he once guided a Force-sensitive person to other villagers to learn about the Force. It is also known that he possessed at least one Force crystal.
Following the transformation of Aurilia into a township, Rohak chose to stay, offering counsel to both the villagers and any travelers arriving in the town. Despite his previous leadership role in the village, the position of mayor of Aurilia was granted to Paemos, rather than Rohak.
Rohak was featured as a non-player character within the Star Wars Galaxies video game, a massively multiplayer online role-playing game created by Sony and distributed by LucasArts, before the game's servers were shut down on December 15, 2011.
