You must be doing something to get the Reians worked up. Adella of the Tiamaranta Expedition asked for you specifically.

Apparently, Reian agents have made a portal directly into the Satra Treasure Hoard.

Gather your fellow fighters and head out to Tiamaranta's Eye to meet up with Rolindel.

Player: Accept.

You're what Ancanus sent, hmm?

Well, needs must.

Player: "What do you mean by that, exactly?"

I mean that we need more allies than we can muster right now.

Have you even realized where you are? You're standing in the antechamber to the Satra Legion's Treasure Hoard. All their war vaults! Ripe for the taking!
