Mirabilis

Mirabilis is a character in Fire Emblem Heroes. She is a Ljósálfar, a resident of Ljósálfheimr, the realm of dreams. Mirabilis is a fellow Ljósálfar and a friend of Peony's. Peony seeks her out as she is the only one who knows how to get to Dökkálfheimr. She has power over daydreams. As her power allows people to dream without falling asleep, she is able to use this ability to enter Dökkálfheimr. From that point onward, she aids the Order of Heroes in their fight against Freyja, though not without falling asleep constantly.
