The Annaj system, which housed the celestial body Annaj, existed within the Moddell sector of the Outer Rim Territories. It was a star system situated at the terminus of the Spar Trade Route. As the Battle of Endor reached its conclusion, with the destruction of both the second Death Star and the Executor-class Star Dreadnought Executor, Imperial Vice Admiral Rae Sloane transmitted a set of coordinates to all surviving Imperial vessels, commanding an immediate hyperspace jump to the Annaj system; this action signaled the de facto end of the engagement.
