The Senex-Juvex region existed within the galaxy's Mid Rim. It encompassed both the Senex sector and the Juvex sector. In the waning years of the Galactic Republic, the Senex-Juvex suffered from the actions of Q'anah's Marauders, a pirate organization under the command of Q'anah, a queen of pirates who was viewed as a local legend in the Senex. This group attacked various ships and settlements throughout the area until an encounter with the Judicial Forces resulted in the Republic issuing a bounty for Q'anah, which compelled the pirates to move their base of operations to the more isolated Greater Seswenna. Sometime after the infiltration of Hivebase-1, the Imperial prison transport Accresker Jail was headed towards Senex-Juvex, the location where the Bandit purges took place.
