I did the Mermaid Marin quest. But I didnt get a tanya's letter which means that I can't complete the key quest? Plz help
She has two quests. For one of them, she asks for Royal Mermaid Linen, that quest does not give the Tanya's Letter as a reward. In order to do the one where she asks for a Tanya's Sword and rewards you with the letter, you must have handed your Mermaid Palace stickers to Captain Stan in field 1 and then taken his other quest.
