Give me cause, Profligate.

Frumentarii (singular Frumentarius), are spies of Caesar's Legion operating in the Mojave Wasteland in 2281.


The eyes and ears of Caesar, his intelligence officers are tasked not only with infiltrating enemy society, but also carry out his campaigns of terror. They operate separately from the main Legion forces and are hand picked by Caesar himself. In 2281, their commander is Vulpes Inculta.

Many frumentarii disguised themselves as couriers, to the point that Caesar had given the order not to kill them, as they might work for the Legion.[1]

Behind the scenes

Frumentarius is a Latin adjective meaning "of or pertaining to grains" or "a grain merchant". This is because of their position in ancient Rome as food gatherers. They are modeled on the frumentarii of the ancient Roman army, who began as food supply officers and soon adapted to be used as spies and special agents in the time of the emperors.


  1. The Courier: "[Legion] Being Frumentarii kept you from killing me in the past. You have no such defense now. "
    Ulysses: "I believed in what I followed then. Kill no Courier, Caesar's words. I honored them. Other Couriers could have been Legion - like me. Now, our allegiances are reversed."
