From the capital, head to the south towards the Dakaav Footpath. With just the two of you again, it will harder to farm off enemies so try to avoid them as much as you can unless you're pretty confident about your skill. You'll have a limited chance to explore the area and the whole map will only become accessible as you progress in the story. For now, head to the middle of the map where the two paths converge. You’ll encounter Eitolon enemies. Defeat several waves of them to trigger a cutscene.
Fight off the mysterious soldiers until the young girl triggers a time stop. Once done, you’ll be carrying her. Leave the area and follow the path to the south leading back to Stahl.
Back in Sthal, bring the girl back to Fidel’s house. The next morning, Miki will temporarily leave the party. Save your game then head to the Mayor’s place next. After meeting up with Victor and his elite guards, leave then proceed to the town’s west exit. Miki and Victor will join the party. Victor’s non-playable allies, Gunter and Hana will join as well. Make your own preparations if you need to then leave the village posthaste.
