A link between eras.

Let me make a few corrections. The mages managed to tear off pieces of land and raise them into the sky. This is how the Silver Cities came to be.

Even while soaring in the heavens, the mages did not lose their connection to the earth. Having lost their faithful Nagas, the guardians of the Academy, the mages descended into the desert, where they encountered fierce Rakshasas, whom they managed to tame. Now they occupy the place of guardians of the Silver Cities.
