Palla is the older sister of Catria and Est, and raised them after their parents died. Loyal to Princess Minerva of Macedon, she was part of the Whitewings, an elite Pegasus squad from Macedon. The Whitewings wanted to join the Altean army alongside Minerva, but when Prince Michalis heard this, he locked his and Minerva's younger sister Maria, in jail to prevent Minerva and the sisters from turning on him. When Marth eventually rescued Maria, Palla and her sister Catria set off to look for Marth and Minerva. When they found them, they joined the Altean army. During the war, Palla developed a crush on Abel.
