Luciana Rune Artwaltz

Luciana Rune Artwaltz is one of the twin valkyries under Gulcasa's command and is the older twin. Both she and her sister Aegina are of eighteen years of age. It is revealed in the Yggdra Union's prequel game, Blaze Union, that she and her twin sister were actually born as princesses of Fantasinia, but an order to assassinate them came right after they were born. A soldier managed to smuggle them out of the country, after which they were adopted by a noble named Marquis Albelt and raised in seclusion within his city. Both she and her sister Aegina were told that they were abandoned because of the old superstition that twins were bad luck, and the two of them spent their lives learning to fight so that they could one day kill the father who abandoned them as well as Yggdra, the younger sister who replaced them.
