Urele-Oresha-Cham Fraternity along with Ashley Pitts, Joshua Ruben and Kevin Beare. He is currently in his Freshman year studying Philosophy. He has reached a positive grade.
He's the cool guy of the fraternity and is often seen playing drums in the campus lounge. His name is a parody of the well known Italian author and adventurer Giacomo Casanova, this also matches the fact that almost all female students at Sim State have crushes on him.
Castor's face structure is similar to Aldric Davis, and Almeric Davis. He also wears 'hint of red' lipstick. When the fraternity is first played, Castor is 49 hours away from the final exam in his first semester. He is the only member of the fraternity that does not have a pre-set Lifetime want. Like several other Sims from Sim State University, Castor starts off with no gender preference.
Many of the pre-made female students at Sim State have crushes on him, though he doesn't seem to be aware of this, and he doesn't have romantic feelings for any of them. The player may decide which direction his love life will take. A good way to prevent extensive drama is to invite any students with crushes on him over, one at a time, and argue with the ones the player does not want to be involved with Castor.
Another trick is to have Castor change the subject to one that the other student is absolutely not interested in. It will lower their relationships, but not as drastically as catching him cheating would. Another useful way to prevent or at least mitigate the drama is to install a mod which eliminates or alters the requirements for jealousy.
