Tome DescriptionEdit

"She is small in size but not in spirit. Leier is a knight in Firenz's unit, and she does her best to tolerate his drinking. When she needs to rant about him, she turns to her good friend Moira. Leier is a fond admirer of Sven's paintings and one day aspires to be a talented artist herself."
