All in-game “Mythril” sales have been discontinued as of today, but remaining Mythril can still be used until service ends. Unused Mythril will be refunded at a later date.
According to Square Enix, while it has been working hard each day to provide good service, it came to the conclusion that it would not be able to maintain satisfactory service going forward.
The final chapter of the main story, more event quests (including the first anniversary celebration), team raids, the Brass Cup, and more will be added to the game before service ends.
In the future, Square Enix plans to release an offline version of Bravely Default: Brilliant Lights that allows users to look back on its various characters and stories. Details will be announced at a later date.
