That statement isn't exactly corrent.
She is the stereotypical mousey librarian, she has no people skills and prefers the company of her books. If challenged she will almost always back down and shy away from a fight, unless the debate is over the law. Her word is final on all matters of state and the laws and charters that govern the Delegates. She has never been one for political favor and stays away from the two waring factions currently within the Delegates. She is shy and quiet only being brought to anger if someone doubts her word on the laws or challenges one of the unchangeable charters.
Leslie was born Cecilia Ann Marie Trent, she was brought into the delegates to be their archival keeper because of her unique ability to remember everything. She was also a perfect personality fit for the job, not having the skills for diplomacy and fighting. She has no taste for blood or sparing or any conflict for that matter. She was also chosen for the job because of her inability to commit to anyone, she has no relationships, no lovers, and no political affiliation so she is a completely unbiased party. The only way she would stand up to another is in matters of the law. Leslie has never been pretty or popular among the Delegates, her rigid view on the law creates a much loved wall between her and the others in the group.
