Hmm. Perhaps the Miragent Holy Templar will know something?

If they're active in all of Atreia, I think they would know about the emblem.

Player: (Nod.)

Meet with Holy Templar Commander Lavirintos.

We may be able to find a clue.

Player: Accept.

Lavirintos is in the Protectors Hall.

It's not far from here, so head there right away.

Player: "Got it."

Is there something you want to know?

I'll tell you anything I know.

Player: "Do you know about this Legion Emblem?"

It's my first time seeing it.

I haven't investigated anything about this Legion Emblem since I became Commander.

Sorry I can't help you.
