From the introduction:
Kazar Brizbane grew up in the town of Nioldra in the world of Greyhawk. At an early age he showed promise of being an excellent mage but because of his family's high standing in society he grew lazy and arrogant thinking that he shouldn't have to perform the same simple tasks that other apprentices had to do and so he was expelled from the mage academy. Thinking that he didn't need the school any more it simply didn't matter to him. While away to Greyhawk city on business for his family, his family's home was broken into and they were found dead upon his return. Having no other family he sought to reenter the mage academy but was refused. Having no other skills or idea of what to do he started to hire himself out as a mage mercenary.
User summary:
Brizbane's Bountiful Book is a little-known, intriguing "net book" of spells.
