A slave in the household of Proconsul Claudius Marcus on the Roman-style planet 892-IV, sent to keep the captive Captain Kirk company on the night before his planned execution.
Drusilla is a slave belonging to Claudius Marcus, the proconsul who governs a world where a Roman empire survived into a twentieth-century level of technology. She appears in the second-season Original Series episode Bread and Circuses and was played by Lois Jewell.
After Kirk refuses to order his crew down to the planet, the proconsul decides to have him executed on live television. Out of a certain respect for his prisoner, Claudius first grants him a comfortable last evening and presents Drusilla, who tells Kirk she has been instructed to please him and offers him food and wine.
She makes no attempt to deceive him and seems content with her position, which illustrates how thoroughly slavery has been made an accepted institution on her world, with guaranteed care in exchange for obedience.
