What did Arcane City really have? Why would countless genius Spell Casters wish to enter Arcane City?

Ever since Merlin had attempted the Mind Tower, he had a dim understanding of why generations after generations of genius Wizards would come to Arcane City by any means possible.

One would have everything that one needed, for instance, Merlin's Mind Power which had been troubling him. He was able to challenge the Mind Tower, each floor offered Merlin some stimulation, expanding his Mind Power in that manner.

Now, Merlin was training to fuse his Mind Power with his instincts. Once he had done so, Merlin's Mind Power would flourish swiftly, and might even break through to an Eighth-level Mind Heart instantly. In addition, he would then be able to complete the ninth floor of the Mind Tower.

Moreover, Arcane City had many other great items such as casting tools. Arcane City was known to be a place where one could find any casting tool.
