To acquire the Wind Spirit Body, Vaan had two main options: physical tempering and medicinal consumption.

Even though the Myriad Sea God Palace was a sea-based Holy Land, it was vast beyond measure, akin to a hundred thousand galaxies or greater. The sheer number of star realms under its control was astronomical.
