Escudo, the Legendary Ore

S1 E5: Alcyone begs Zagato for another chance to kill the Knights. They encounter Alcyone’s lake monster in their travels. They jump into the fountain of Eterna to acquire the Escudo, but a test awaits them. They are attacked by visions of their loved ones, and are reluctant to fight back until they are reminded of the nature of the apparitions. They summon new magic spells and defeat the images. As they approach the Escudo mineral at last, Alcyone once again intervenes. She, too, wants the Escudo. The mineral rushes into the girls and renews their strength. They defeat Alcyone with their magic, and rush back to Presea. She will make new weapons and awaken the legendary Machines. On hearing of the defeat of Alcyone, Zagato is angry and sends another warrior, Ascot.
