Kaizen's first and last visit to Olaynore, the famous Wizard's Tower, ended peacefully, in a way.
On that occasion, a rebel wizard called Adohorn kidnapped Alina Sylly, the daughter of the former librarian of the Library of the Magi. He did this because he believed that Alina was the only one who could know the location of the book of legend, the Book of the Deep. According to the legend, this book could make any wish come true, even if that wish went against Olaynore's natural order. This book could change everything and take the Elders of the Wizarding City off their pedestal at last.
However, Adohorn wasn't the only one after the Book of the Founders. Although he had an alliance with a Citadel mage called Egelza, she was already in the sights of the Elder Mages and just as the final battle was about to begin, with Kaizen on one side, an Elder Mage on the other and Egelza in the center, everything was interrupted by the Guardian of the Forgotten Forest.
