The Zavian Abyss ambush took place as a trap set by the New Republic for the Overseer, an Imperial II-class Star Destroyer. The goal of this trap, sprung within the Zavian Abyss, was to stop the Overseer from discovering Project Starhawk. As part of the ambush, the New Republic unveiled their freshly finished Starhawk-class battleship named Starhawk, compelling the Overseer to withdraw from the engagement.
