It has been exactly One hundred years since the whole Darkstalker incident.
And Pyrrhia has changed a little bit.

For one thing, seven years before the current present day Pyrrhia, A massive crack formed suddenly between the Sandwing and Icewing kingdoms.

Another thing, fifty years ago, Jade Mountain Academy had been attacked by an unknown group of rogues. The school was forced to shut down due to the safety of the students, and to this day nobody has tried anything to fix the school, most who try in attempt usually go missing the very next day, no matter where they are, as long they visited there, they have gone missing.

And lastly, Brilliant Academy had been built by the only known (alive) Skywing animus: Cinderfell.
The school had been built not only to replace Jade Mountain Academy, but to serve as a (temporary) peace treaty between all of the tribes.
