Hephaestus is the God of Smithing. His most famous son was Cycnus.

Cycnus
He had a son with Aphrodite called Cycnus. Hephaestus created a Spear that could kill anyone it pierced the skin of, which he gave to son. Cycnus set up his home on the road between Joka and Formo. He made a temple to his father out of the heads from his victims. Cycnus was killed by Achilles and Hephaestus went to avenge his son. Achilles beat back Hephaestus but Athena told him not to kill the God. Hephaestus then fled back to Olympus.
