In this graphic adaptation of the American folktale, John Henry is the strongest elf in Gem Forest, able to carve out a perfect mining tunnel with a single swing of his hammer. When Snotsworthy the gnome invents a machine that digs tunnels without the need for paid workers, John Henry challenges the gnome to a contest on sinister Witchfinger Mountain, home to a tribe of sleeping orcs.
