Presidio Army Fort

Data and Guinan stand in Data's hotel room, plotting access to the Presidio Army Fort on San Francisco's rugged bluffs. This high-security U.S. military installation guards a hidden mine shaft—the sole entrance to the cavern housing Devidian threats. Guinan's skepticism mounts as she details the fort's strict perimeter patrols, barracks ringing with orders, and ironclad rules blocking civilian digs. Salty Pacific gusts whip the grounds outside, amplifying the isolation and risk of breaching its defenses to reach the underground lair.
