The following incident occurred in 403 BBY.
- A vessel belonging to the Corporate Sector Authority, named Commerce, vanished while trying to perform an orbital scan of the planet Nyriaan situated within the Luire system. This happened during a scouting mission. Later that year, certain survey ships from the CSA managed to verify that the planetary atmosphere and its magnetic field prevented standard scanning or viewing of the world. Consequently, no further communication was ever received from the Commerce. [6]
