Every large government-approved organization was required to have at least one or two opulent, monumental architectural wonders as their headquarters. For example, the Warriors' Association had the Hall of Fame and Valiance; the Alchemist's Association had the Titan's Core; the Doors of Conundrum had its prized Illimitable Library, and the Church's headquarter was the Temple of Auguries. However, the Sorcerer's Association's Babel Tower and Cloud City were, without question, the most beautiful and majestic of them all.
