Aherne Sutton Dark Heresy
Spurring is the somewhat distasteful practice whereby nobles invite a middle-hive patron to a party where they are all acting out a famous play. The unwitting hiver is injected with Spur to enhance their entertainment value and they are used to provide amusment to the other guests.
If the hiver does well they get a good night out and some money, if they don’t they continue to get injected with more Spur until they either overdose or perform well. Either way it doesn’t usually end well for them.
A true noble would not be phased by this commonplace practice.
