They spent most of their time cleaning, rarely having any free time. Very smart, very skillful in math, they're also very independent and hate being told what to do (by any other than aubade). Pretty hard to approach as they can come off as quite rude. They enjoy teasing, provoking and making jokes at the expense of those they dislike or have hard feelings towards. Because of their long work days, they're most often very tired or stressed. Lacustrine has some narcissistic tendencies.
