Ghost Hallow is a Ninetails encampment on Microtech that uses a downed Reclaimer as part of the outpost. You can obtain a mission to clear it out or you can travel directly to the outpost and kill all of the Ninetails. If you do this however, make sure you have the call to arms mission so you get paid for each person you kill.
The most popular feature and what makes this location so iconic is the tribute to Hoban Washburn or Wash from the movie Serenity. Wash was killed in the end by the Reavers when a spike came through the cockpit window and then through Wash’s chest as he was claiming, “I am a leaf upon the wind, watch how I grrrrrrh…..”
We will miss you Wash, may you always fly true…
