As you know, the Victory Insignia of the Arena of Harmony can only be obtained by completing the challenges inside the Arena of Harmony.

So, if you're here...

It is a very hard, arduous challenge to find reliable companions and improve your skills together.

However, what you earn after such hard time will be of great value. Believe me.

You have endured many trails, pushed yourself beyond what was expected, and now you stand tall.

You have earned the highest praise of the Sanctum Headquarters, as well as this reward.

Seiran informed you that Sanctum Headquarters was offering a prize in an attempt to foster strong Daevas and defend the Tower of Eternity. She then told you to retrieve the Victory Insignia from the Arena of Harmony.

Upon your return with the Victory Insignia, Seiran gave you the prize you were promised.
