Hephaestus (Roman Vulcan) was son of Zeus and Hera. As god of fire he was the supreme craftsman, building the wonderful houses for the gods on Olympus, and doing all their handyman work for them. His own house/workshop was fully automated, with robot maids and furniture with artificial intelligence. He was also lame, and thrown from Olympus by his mother (Book 18) or father (Book 1), in shame at having produced him. But he still pulls the girls - he is married to the beautiful Charis (and in the Odyssey to Aphrodite). He makes the fabulous new armour for Achilles in Book 18, to please Thetis, who looked after him after his fall from heaven. He helps with his fire when Achilles is struggling in his fight with the river Xanthus.
