The Echo Horn served as a tool crafted by Glenna Kip to manipulate the Zixon, who are the native species residing on Minfar. It was intended for use by the Galactic Empire. This device possessed the power to govern any collective that perceived its sound. Subsequent to the Empire's collapse, the First Order journeyed to Minfar with the intention of acquiring this weapon, but the Resistance ultimately achieved its destruction.
