Ptah's Clique: Auto Club and Woodshop
These guys can make anything. Horsehead bookends? Of course. Plastic napkin holders? Easysauce. For their final project, they built a biodome out of toothpicks and glue, and installed a full set of solar panels in it for their final class project.
Various Algonquin-speaking tribes in North America know this god well. He makes things for them, from birch trees for canoes to animals to hunt. He's also good at carving flint arrowheads.
Izanagi and Izanami
These two Japanese deities are always together, but they fight a lot. When they aren't fighting, they create beautiful things. The islands of Japan were their biggest class project.
Hephaestus, or Vulcan to the Roman kids, is the king of the metal shop. If he's not making weapons or melting down copper bars to make a volcano out of the forge, he's shaping beautiful things for extra credit.
Kothar is a Semitic god, who is supposed to be a top-notch smith and craftsman of all kinds. A few of his more famous feats were crafting a bow for the mortal Aquat, building a fabulous palace for the warrior god Baal, and making two magical clubs for Baal, with which the warrior god defeated his enemy Yamm.
Wayland the Smith
This legendary blacksmith pops up in Norse, Germanic, and Anglo-Saxon legends. Like Hephaestus, he was said to walk with a limp. Wayland was hamstrung by a King Niðhad, who kidnapped him and forced him to forge things for him. The blacksmith got some serious revenge on the king, though, when he killed Niðhad's sons, made goblets out of their skulls, and tricked the king into drinking from the cups. (Yikes.)
