“I do not think so. Nor do I think you should feel troubled for our sake. You are our home, more than Medon; our true house is the sky around you. We will always serve you, Commander, through thick and thin. I swear it.”
—Palla to Minerva, Fire Emblem: Shadow Dragon
Palla is the older sister of Catria and Est, and raised them after their parents died. Loyal to Princess Minerva of Medon, she was part of the Whitewings, an elite Pegasus squad from Medon. 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.
In Fire Emblem Gaiden, Palla and Catria journeyed to Zofia in search of the kidnapped Est, eventually joining with Celica's army to help them save Est and to aid Celica on her journey.
In Fire Emblem: Mystery of the Emblem, a rebellion against Minerva's rule broke out in Medon and Palla was forced to flee, meeting up with Julian and learning that Lena and Maria were captured by Gharnef. She joined Marth's army in order to save Minerva and Maria. After the war,she pushed aside her feelings for Abel and continued serving Medon.
Palla has a very high skill growth, but her speed is awful for her class although it's made up for with her high base speed. If you wish for her to stay as a flying unit, promoting her to a Dracoknight is a better choice because it fits her high strength and skill and her low speed. If you want to boost her speed, consider changing her class to an archer or a myrmidon.
Palla, Est and Eldigan are the only recruitable DLC characters in Awakening that do not have recruitable SpotPass versions.
In a support conversation with Est, it is revealed that Palla keeps a locket with a picture of her late mother in it, as she is the only one of the three who was old enough to remember their mother, and she has yet to show it to her sisters.
