you don't receive anything or send anything but the code does work. Don't forget: you'll need to send four messages to Prince Allus of Saronia. The final message he gives you will unlock this chance. I'm not exactly sure about the requirements of getting the mMessages from him. I believe you'll need to send four to the Old Men before the
Prince will send you the message telling you where to go.
Once you've obtained the last message from the Prince, get on the Natalius and make you way about halfway between the floating landmass and the southern tip of the Dalg continent (the one with all that wind)
