START
After obtaining the Spiritual Power of Wind, head to the Great Camelot Bridge where a merchant will tip you off to the location of an Iris Gem in Horsa Village. Head to Abandoned Horsa on the Zaphgott Moor, where you encounter Stheno. Sorey hesitates when she cannot be purified, and the hellion escapes. She leaves behind an Iris Gem. As you leave Horsa, a skit will trigger. Afterwards, you will acquire the fashion attachment Elf Ears.

Head to Pendrago Shrinechurch and check the bookshelves to learn about the Forton sisters.
After defeating Tiamat, return to Glaivend Basin and speak with the guard who has found an unmapped village. Enter the remains of Abandoned Village Forton to take on both Stheno and Euryale at the same time. Defeat and purify them to see the end of the sad Forton sisters’ storyline. You will also acquire the fashion attachment Angel Halo.
