Wind Realm

The Wind Realm, known in Japan as the Plane of Wind, is a realm born from the concept of wind in the expanded lore of Magical Vacation. Like many of the other realms that are not seen in the game, the Wind Realm is only briefly mentioned. According to Magical Vacation Complete Guide, a special mineral called windstone is found in this realm, which is used to craft winged studs.

History
It is said that over 1000 years ago, the first tribe of felins founded a country in the Wind Realm before migrating to other realms, much like how canins came from the Wood Realm.

Magical Vacation
If the protagonist beat the game's final boss with darkness as their element, they set out to travel various realms after graduating from Will-o'-Wisp Academy, beginning in the the Fire Realm. After they became a living legend in over thirty countries and twenty realms, they passed away peacefully in the Wind Realm at the age of 87.
