Hephaestus was the god of fire and the forge, which is a tool that blacksmiths use. Son of Hera and Zeus, he was thrown off of Mt. Olympus as a child and his legs got deformed as a result. Though he is married to Aphrodite, she doesn't enjoy his company and starts to date Ares instead. Hephaestus provides the armor for the gods and heroes like Achilles.
