Castellaneta is a human tourist station in geosynchronous orbit on the "sunny side" of Saturn's outermost ring, in the Sol system. The station features a zero-gravity resort with a swim-up bar and club, known for over-priced alcoholic beverages. UNSC Marine Edward Buck had been sent to the station on mandatory shore leave in 2545, where he first encountered Office of Naval Intelligence operative Veronica Dare.
