Tach3on Site
The Tach3on Site is a Pre-Raid structure located south of Nogales, today in Santa Cruz County, Xarslasja. It is so named due to a sign that read "Future Site of Tach3on's Base." This base was either destroyed shortly after construction or was never finished, as all that remains is the foundations of a house with one chest, the start of a mine, and a small dock labeled the "Dock of Shame."
Today, the Nogales-Arcosanti Line has a stop there, between Tucson and Nogales. It's the most convenient way to access the town of Naco by rail.
The United Ŋations built peacekeeping structures around the Tach3on Site during the Santa Cruz Crisis, presumably to protect it from being damaged should open conflict take place.
