Direct Neural Programming had been the dream of many education "reformists" and technocrats. The perfect way to teach skills, divorced almost completely from the requirement that human teach human. One single avatar of a skill could be used to propagate that skill until it became obsolete. Billions were poured into its development and marketing, thirsted for by corporations, the military, and politicians, each group wanting the surface and the sinister. But it was not to be.
The peasants of the wood use crudely carved symbols to ward off wolves. They think the symbols are emblems of purity and goodness and that keeps the wolves away. The symbols work, but not for the reasons the peasants believe...
The symbols are actually arcance evil symbols which the wolves know and fear, but to which the peasants are oblivious. So how gullible are the peasants going to be when a strange horned man displaying the symbols on his shield turns up and asks for their allegiance?
