In a far kingdom of ice and snow a wild, red-maned filly is found by an earth pony called Maple. She becomes an apprentice of Maple's friend, a royal magician, unicorn mare Blizzard who gives her name Eveningray, and raises her along with her own daughter Spring Brook. One day guards controlled by an evil usurper take Blizzard away. But the young mares are not ready to fight the enemy so strong yet.
