The Book of Khadgar was a spellbook that once belonged to Khadgar. When he entered the Dark Portal, he left this tome behind. Later an orc far seer acquired the book, only to be slain in cold blood by a powerhungry high elven mage called Alayin Glitterhelm. Unfortunately for Alayin he was killed by the tome's guardian, a wolf-like creature made out of shadows.
