Additional information:As a republic player you get this by doing the following:
Start at the taxi in Lower Industrial Sector, go east to the Imperial Intelligence Gadget Warehouse.
Once there you take the the Systech east elevator and continue to Upper Office Atrium.
From there you go to the Lower Office Atrium and continue to the Systech west elevator.
Once at the Systech West elevator take care of Imperial L50 Elite quickly click the elevator button, and go to the Republic Research Division .
Enter the Republic Research Division and make your way to the Imperial taxi at Upper Industrial Sector.
You’ll have to pass through an Imperial base filled with lvl 50 mobs but I got through with only two deaths at lvl 33. I got the codex entry when standing pretty close to the taxi vendor.
We would like to thank Lirod , Stefan and Xinra for additional information.
Original Game Codex TextThe Upper Industrial Sector is the center of manufacturing and industry for Republic corporations on Nar Shaddaa. Here, centuries-old droid construction facilities stand next to the cluttered offices of startup firms desperate for resources and space. The companies share a common need for heavy security and compete for similar clientele, ensuring that this sector remains a choice location–but are otherwise wholly independent. For a corporation headquartered in Republic space, Nar Shaddaa is a convenient place to develop technologies restricted by Republic laws–or from which to deal with foreign parties. The Senate frowns on these activities, but just as often turns a blind eye when these same corporations bring their innovations back to Republic worlds.
