Vulcan is Hephaestus' Roman form. As Vulcan, he becomes more disciplined, militaristic, and warlike. While the Greeks envisioned Hephaestus as a benevolent and clever being, the Romans believed Vulcan to be the god of volcanoes which gave him a greater respect and fear among their people. He may have children or legacies at Camp Jupiter near San Francisco.
Compared to his Greek counterpart, Vulcan had a stronger association with fire's destructive capabilities. As such, he was worshiped primarily to obtain his protection in averting fires, so there were numerous shrines dedicated to him where fires were most feared, such as areas near volcanoes and where grain was stored, especially at the port of Ostia. An interesting note is that his shrines stood outside of the walls of cities.
Being determined to shun the company of the other gods Vulcan established his home in the heart of Mount Etna, where he fashioned a giant forge. His workers were the one-eyed Cyclopes. He created a golden throne for Juno, and fashioned magical thunderbolts for Jupiter and Cupid's arrows.
He is said to have fathered Servius Tullius, one of the Kings of Rome, who proved his parentage by the useful talent of being able to cause fire to descend on his enemies. He was the patron of artisans and blacksmiths. In these late times he was depicted as a smith in a tunic that freed his right arm and shoulder, and with an anvil, tongs and hammer.
His festival was the Vulcanalia, falling on August 23rd, the period of greatest drought and highest fire risk in Italy.
When Leo is claimed by Hephaestus, Vulcan's Greek aspect, Jason says that the symbol hovering over Leo's head was that of Vulcan. This cause the campers of Camp Half-Blood to look at him and upsets Leo who says that he does not even like Star Trek. Annabeth then corrects Leo, saying that Vulcan is the god's Roman name, whereas Leo's father is Hephaestus. Later, Leo asks Will Solace what was up with the name Vulcan, to which the latter replies by saying that the campers use the Greek names as those are the original ones.
