14. Marie Event #4 --> 2-3 Felicia is seen with Marie at this event.
- Part of a forget-me-not. Wikiet-3, north of Traveler's Distance save point, across the huge gap between the islands. Search south east of the mountain. The e-guide also doesn't say whether this is Marie's event or not, so please correct me if I'm wrong. The Marie events all have a unique music anyway, if that helps.

- Rofia Spring. Brosste-3. At the very eastern side of the map, there's a small patch of forest that's next to the large tree-trunk tower. Search around the small lake. Again, the e-guide doesn't mention this, so I'm unsure if this is the right event. It sounds like it, and I only figured it out by process of elimination. Save before, and correct me if I'm wrong.
