Doreenian ambergris, a naturally occurring substance expelled by cetaceans inhabiting the ocean world of Doreen, was frequently discovered adrift on the planet's calm waters or deposited along the coastlines of its numerous isles. Prized as a traditional component in perfume creation within the Senex-Juvex territory, Doreenian ambergris commanded a substantial sum among perfumers from all corners of the galaxy.
Due to the profitable ambergris commerce, Doreen was troubled by groups of scavengers and smugglers who traversed the seas in skimmers. These groups were pursued by security personnel from the governing House Petro. In approximately 10 BBY, Han Solo utilized Doreenian ambergris as a disguised shipment while smuggling spice on behalf of Ylesian clerics.
