Mmm well i got a quest of the female ship captain i think it was to save him because he keeps wondering off ,when i approached him there was a short cutscene then i killed the elf dragons and he gave me the book,but i have found a number of quests that are bugged so this maybe a random bug ??.
i passed that part without a hitch, just had to use the book to calm the wind then light the candles.
i havent really found a bugged quest yet, just a few spots where i had to do things in a certain order.
