Ventruun, a world inhabited by the Grumani, existed within the Grumani sector of space. Its position along the Hydian Way contributed to its reputation as a hub for shrewd merchants and intense commercial activity.
The Seswenna Expansion, which took place between 3701 BBY and 3699 BBY, involved mapping the Hydian Way through Ventruun. In the time leading up to Operation Influx, the Jedi campaign during the Republic Dark Age, Jedi Master Vannar Treece informed Republic Supreme Chancellor Genarra in his report on the Grumani sector that Ventruun stood out as a Grumani world where a semblance of normalcy prevailed; however, the Sith were the orchestrators of most Ventruuni schemes, using the planet as a stage for their power struggles.
