She lives a hundred years ahead of Max's time, in an unknown part of the land.
Monica is a 15-year-old friendly and kind girl; she is also wise and very cautious. While she is generally shown as dutiful, helpful, and strong, and sometimes she also has a mean temper and can sometimes be offended easily. Overall, she is giving, charming, and competitive.
Monica is not selfish; she is, in fact, probably the most generous character in the game. When she meets Max, she quickly becomes his reliable ally, and also becomes very protective of him. She is a princess, and like Max, she does not take advantage of her wealth and power. She is adventurous, and loves to explore.
