Leah and Fatin decide to go explore the north side of the island... alone.
15th century alternate history. Fatin/Leah, Kirin/Dot
Fatin learns that though their scars will heal, they will never disappear. (She also learns that that's okay.)
Fatin can borrow Leah's heart for the rest of her life, and Leah won't mind. (AKA, each time Fatin borrows something from Leah, Leah's feelings for her grow.)
