Reginn

Reginn is a character from Book V of Fire Emblem Heroes. The younger sister of Fáfnir and Ótr, she is a princess of Niðavellir. Reginn is a kind-hearted, gentle princess who cares greatly for her two brothers. Fáfnir and Ótr's sudden change in personality, which she states are full of rage, is deeply concerning to her. Despite this, she faithfully obeyed their orders in the hopes that they may one day return to their former selves. She even cried when she felt that she had failed them after being defeated by the Askran army twice. However, her encounter with the Askran army proved to be a window for her to ask someone for help in the hopes of returning her two brothers to their original selves. Considered as the tomboyish Niðavellir royal, she claims to be an excellent cook and is eager to show her cooking skills.
