Imaged by the Cassini spacecraft, the terminator of Saturn's moon Dione passes through Dido crater, with its central peak. Just above it, in sunlight, on the sub-Saturnian hemisphere of the little moon, are the twin craters Romulus and Remus (Romulus is the larger one). In The Quiet War, the city of Paris, Dione, runs down into Romulus crater on the slope of the rimwall shared with Remus crater.
