In an ancient shipwreck in the Sheogorad Region, it's possible to find a book titled "Capn's Guide to the Fishy Stick".

This is a reference to a popular tradition started by forum member "Captain Eldrad" in the official forums years before the release of the game. Older members of the forum used to welcome new members by greeting them and posting an image of a pirate holding a fish stick. The Bethesda developers honored this tradition by putting the book into the game.

The book claims to be the definitive reference to fishy sticks throughout Tamriel, but sadly its contents state that "the pages are so smeared with fishy stick sauce it is impossible to read any of them."
