The Magical Elements of the Periodic Table Presented Alphabetically By The Metal Horn Unicorns draws inspiration from the previously established Journey To Osm unicorn books. In that book twelve main characters each have a metal horn and hooves correlating to the properties of certain metals. For example, in this novel, Cuprum—the Copper Horned Unicorn—can purify water and control tornadoes with her powers as they develop throughout her story arc. Additionally, she can make rivers dance; this is an ability yet to be seen in any metal element!
