Cesium lives in a moderately sized home with a minimalistic appearance. His place is very geometrical inside and out, and the common/ public areas are kept neat and tidy and gives the illusion of having plenty open space. He just doesn't keep a lot of things out in the open, save for a few decor to make the place look less dull. Aside from a lot of white and gray, his decor also consists of sky blue accents, either in items or a certain wall painted differently to show some style. His applicance also match each other in each room; the kitchen has a sleek stainless steel finish to most items and applicenaces he owns, same for the bathrooms for the sink and shower. His bedroom is kept tidy as well, with basic but comfortable sheets. In every room he has, there is at least one clock, either analog or digital depending on the room. He has a basement which is similar to what wone would call a Museum of Clocks; it is a large room with precise climate control that stores the many different types of clocks he owns. Most are very old or antique that he collected over the years, others are his personal favorites.

Cesium is very good at math. Math was always his favortie subject. His second favorite would be physics, and his third would possibly be history. It all relates to his interest in time. Someday he wishes he could calculate the exact timing on when the universe started and see how long it has been since... the beginning of time. So far he tried to formulate a couple theories but none has been tested or checked to see if they could work as of yet. It's all still one big planning phase to him until he can find that Eureka moment. Aside from that, he likes to learn about the different methods of timekeeping people have come up with in the past and how they worked. They could be simple or complex and varied from the sundial to the hourglass and more recently to digital timekeeping, and how in every advancement how it was created to become more precise in its timing.
