Gods are a race of powerful immortal beings that are commonly worshiped by mortal inhabitants of certain realms. There are several distinct pantheons of gods, such as the Greek Olympians or the Norse Aesir and Vanir pantheons. Every god in each pantheon fills a certain role, such as the God of War or 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 his death.
Rarely, a mortal can ascend to Godhood after a God is killed and their place in their respective pantheon is available.
