Go to 'A Pirate Campsite' in the Industrial Seas near Bengal.
Kill all of the pirates at the campsite, then move west to 'In a Cave' and kill the pirates there.
Get the key to the cell from the corpse of one of the pirates in the cave.
UNLOCK SOUTH. OPEN SOUTH. and move south.
The opium seller's son will give you a wooden token.
Now go to 'An Opium Warehouse' in Bengal, GIVE TOKEN SELLER
You get the whois ...ONCE RESCUED A YOUNG LAD FROM THE CLUTCHES OF EVIL PIRATES!
You get a silver eyepatch!
If you repeat the quest the opium dealer attacks you, and your whois is replaced with: ...HAS BEEN SEEN IN COMPANY OF PIRATES AND MAY BE CONSPIRING WITH THEM!
