A young mechanic within the Ptolemaic Army, Caroline is responsible for most of the Ptolemaic Army's machinery, based off of other armies'. As one of the youngest members in the Ptolemaic Army along with her passion for machines, Caroline is somewhat of a troublemaker. Due to her position as the head mechanic, she also has considerable authority over others and is also capable of leading field operations if necessary, though this is often to obtain a machine that gets her interest piqued.
