Lucia is known as the Princess of the Blue Star. Her sole purpose was to revive the Blue Star after Zophar's assault. However, when Zophar is on the verge of resurrection, she is reawakened in order to prevent his return. Lucia was isolated for her entire existence as her only purpose was to heal the Blue Star without any interaction with the people of Lunar. Lucia knew nothing of human emotion either, so initially, she is very serious to the point of being insensitive. But not anymore.
