Eiselstein, Armony

Armony Eiselstein, known as "Armony Angelstein" in Japan, was a fledgling young alchemist under the tutelage of Edward Elric and the daughter of Professor Wilhelm Eiselstein, esteemed scientific researcher. Armony is a main supporting character created specifically for the 2003 video game Fullmetal Alchemist and the Broken Angel.

Aforementioned above, young Armony was the second daughter of Wilhelm Eiselstein, and youngest sister to the deceased Selene Eiselstein. The memories she held on to after Selene's death is all that remains of her memory, that alongside a lone grave. The interim of Armony's life, until she met the Elric brothers is as of yet unknown, however, one portion of her upbringing is Alchemy. A subject which intrigues Armony enough to pursue but her father is none to keen on the hobby, quickly forbidding Armony from practicing alchemy, the passion of his career.
