Aldraig

"As I stated in response to your initial query, the shipment departed as planned from Aldraig in the Alderaan sector."

- Senator Bail Organa, to Chief Investigator Axvering

Aldraig was a location in the Alderaan sector of the Core Worlds. During the early rebellion against the Galactic Empire, Senator Bail Organa of the Imperial Senate attempted to cover up a theft of a UT-60D transport shipment by having an Aldraig data clerk mistakenly route a shipment of U-wings to Coruscant through Baylagon.

After the Galactic Empire's Imperial Security Bureau launched an inquiry led by Chief Investigator Axvering, Senator Organa acknowledged to Axvering about the data clerk's mistake, but believed that another layover would would not have been an inconvenience to a competent pilot. The UT-60D transports eventually reached the Alliance to Restore the Republic.
