Memoirs of Sir Cabirus

Memories of Sir Cabirus comes with Ultima Underworld I. It is 30 pages long and has an unusual look, as its front is totally black. In-game, Corby, the scribe of Sir Cabirus, is the author of the book. In real-life, Mike Harrison has written the book.

The following topics are part of the book:
 * The proclamation
 * History of Britannia
 * Inhabitants of The Abyss
 * The classes
 * Runic Magic
 * Bestiary
 * Afterword

The reader has to remember that the book is intended to put Sir Cabirus' work into a good light. Therefore the Abyss-colony is painted in better colors than it actually every had been, althrough the afterword makes it clear, that in the end everything has broken down.
