Gods are a race of powerful, ageless beings that are commonly worshiped by mortal inhabitants of certain realms. There are several, distinct pantheons of gods, such as the Greek Olympian’s or the Norse Aesir and Vanir pantheons. Every god in a pantheon fills a certain role, such as the God of War or the God of Light.
Oftentimes, each God has a counterpart in other pantheons. For instance, Týr is the Aesir God of War in the Norse pantheon. However, in the Greek pantheon, the God of War was Ares, who was later replaced by Kratos after the latter killed him. According to Kratos, the gods care nothing for their worshipers. Worshiping them is foolish and men should not pray to monsters, however, Tyr is a notable exception as he is shown to greatly care about mortals.
Despite being immortal and immune to all forms of mortal harm, diseases and aging, Gods can still be killed, but only by the power of a God, either by another god or someone wielding a godly weapon. Kratos kills the entire Greek Pantheon in his quest for revenge against his father, Zeus, and thus leaves all of the Greek world in Chaos by the end of his vengeance.
