Altar of Hephaestus is a temple building chain in a Total War Saga: Troy. These can be built exclusively in province capitals. Only a single temple can be built in each province. Each temple built earns 10 additional favour gained from a hecatomb. Each new temple also increases the cost of a hecatomb by 25%. Temples enable the recruitment of priestesses. Every temple increases the capacity for fieldable priestesses by 1 up to a maximum of 3.
The god of artisans and blacksmiths, Hephaestus forged nearly all the great weapons and armour of legend, including Apollo's bow and arrows, Diomedes' cuirass, and even Zeus' mighty thunderbolts. According to the Iliad, Hephaestus was cast out of Olympus by his father Zeus, but later returned to the divine realm where he put his unrivalled skills in service to the king of the gods. Such was his mastery of metalworking that he was said to have created wondrous metal automatons to assist him with his work.
