The Grand Barter can be found at Levski on Delamar. This article contains a map so you can find your way around.
From Hab Unit to Fleet Management Consoles
This is one of the easiest locations to start in. If you wake up in the customs hab unit, when you exit the hab entrance the customs area will be on your right. Otherwise, your left.
The Fleet Management consoles are behind the customs area on the upper floor very close to the hab units.
The diagram shows the upper and lower levels of Grand Barter which is the focus of the location. The mission giver can be found at the Borehole Station. The Greycat mining tool can be found at Conciencious Objects in the upper level of Grand Barter.
Note: External air-locks can be found at the highest level (not shown on map)
Visit the Grand Barter
