This sourcebook contains details of the Towers of High Sorcery. The Towers of Wayreth and Nightlund are explained in great detail, while the "lost" Towers of past ages are presented for the first time anywhere! New prestige classes, spells, magical items, and artifacts are presented—many having been seen only in Dragonlance fiction up until this point. The Test of High Sorcery, an important part of the career of any Dragonlance wizard, is explained in detail, with detailed steps on how to design a Test either as a solo-adventure for the wizard character or a dangerous quest for the entire party!
