Crow's Foot is the steadily adopted language of scholars being used to record information. It's said to have been taught to the creatures of the Farworld by The Mother herself by sending an envoy in the form of a crow.
Crow's Foot is starting to be used in tandem with Archaic in order to convey messages - usually with Archaic being used to convey a general idea while Crow's Foot conveys more detailed and specific information.
This message for example is displayed with the Archaic symbol, baga but instead of being used for the sound, the snake in general signifies danger. This particular snake is brightly colored conveying a very dangerous area while the Crow's Foot says, "Danger! Farcreature!"
As the snake is meant to be interpreted as venomous and easily spotted, the reader is meant to understand that the farcreature of this area is dangerous but confrontation can be avoided with caution.
