A world at the mercy of a mad Solar Deity
Created by the god of madness, one must be at least a little insane to be able to use them. These tools cause much confusion to those that see them in action and are guaranteed to cause misunderstandings.
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?
