This quest becomes available once you’ve completed Investigate Neretzes’s Folly by speaking with a noble from each of the major factions.
Where to Find Istiana at Epicrotea
If you’re looking for Istiana immediately after receiving the quest, you should find her in Epicrotea, a large settlement located in the Northern Empire. If you’ve waited a few days or for whatever reason you can’t find Istiana at Epicrotea, you can open the encyclopedia and search her name. You’ll then be able to see where she was last seen in Calradia, giving you an idea of which region to look for her in. Regardless of the settlement you find her in, you should check the tavern and the streets, as these are the primary locations where she can be found. Alternatively, just select her avatar from the top right of the screen when you interact with a settlement.
Tell Istiana: Save the Empire or Undecided?
When you speak with Istiana she’ll ask what you intend to do with The Dragon Banner, should you come into possession of all three of its pieces and repair it. Istiana would like to see the Empire saved, so if you want to know where a piece of the banner can be found, you should tell her that you also want to save it. If you tell Istiana that you haven’t made up your mind, she won’t tell you anything.
Where to Find a Piece of The Dragon Banner at Hideout
After speaking with Istiana, the location of the hideout where the piece of The Dragon Banner can be found will be automatically added to the tracker. The hideout should be close to the settlement where you first met Istiana, which is just northwest of Epicrotea if you found her there. All you need to do is travel the hideout and attack it, clearing it of all enemies. You won’t need to look for the banner during the fight, since it will be acquired automatically once the attack is over. The quest will end after this.
