Cygnus's Last Request

[Name], I know you've done so much already to help us. But could I ask one more favor of you?

Though I've accepted Shinsoo's power, Ereve's army is not ready to take on the Black Wing invaders. Could you please join the battlefield to protect Ereve?

Thank you. May Shinsoo's blessing be with you...

(Talk to Kiriru to ride the Airship to the Battleground.)

Please...think of Ereve.

Please save Ereve.
