In order to receive this mission, you have to speak with the wife of Adril Arano – Cindiri Arano . She can be found at The Retching Netch or at the streets of Raven Rock . She will tell you that the ship carrying her book has sunk nearby the shore. If you manage to retrieve the precious volume – the Lusty Argonian Maid Folio – you will be handsomely rewarded.
The wreck can be found at the southern shore of the island, nearby Old Attius Farm. Bandits have made camp around it – in order to get inside and retrieve the precious book, you will have to defeat them. Don’t worry – they aren’t very strong, so fighting your way through them shouldn’t be a problem.
Once on-board the ship, head below deck and search for the treasure chest with the Lusty Argonian Maid Folio. Return to Raven Rock and give Cindiri Arano her book back. She will in return give you a magical item, the quality of which depends on your level.
