Tales of Mortals, told by the Feywilds.
They talk about some humans with bloodshot eyes and axes for hands, burly giants with an edge to their hands clearing wide swaths that destroy our homes (in reference of Lumberjacks). Lanky men with yellow eyes like cats (hunters), matted wings beneath their arms that spit out poison darts, launching them from their hands and coughing up spiderlike webbing made of iron! Those that eat the same toxins an pollutions, spitting them out casually. The only thing that can scare them off are magic, illusions, and shiny rocks of gold and gems - but they're always wanting for more... In addition to hunting Pixie for their wings and pixie dust.
