After reaching his palace, Marth defeats Hardin, obtaining the Darksphere. The spheres are placed on the Fire Emblem, which becomes the Shield of Seals. Marth discovers that Hardin wasn't really evil and was possessed by the evil priest Gharnef himself through the Darksphere. He then heads to Dolhr where Gharnef lurks. After Gharnef is defeated, all that remains is the new reborn Medeus, guarded by Earth Dragons and possessed clerics, including his sister, Elice, and Princess Nyna. The Shield of Seals emits a power that forces the Earth Dragons to retreat, giving Marth's army the opportunity to save the clerics and for Marth to defeat Medeus once and for all with a slash of Falchion. Afterward, Marth is declared Emperor of Archanea and is finally married to Caeda.
