The Endor tracking station, once a neglected research facility, was repurposed by the Rebel Alliance into a surveillance hub for observing starships operating within the Endor system. It was this station that initially identified an approaching fleet of Nagai starfighters just prior to their assault upon the planet's surface. During this attack, a band of Maccabree combatants launched an offensive against Princess Leia Organa and her Zeltron assistants at the monitoring base, an assault that was only thwarted by the arrival of Luke Skywalker, who compelled the warriors to withdraw.
