Gods have an array of powers and abilities, typically related to a specific theme or aspect of mortal life, such as war, love, wisdom, or death etc. Only a small number of artifacts have the power to kill a god. Gods of sufficient power are also capable of killing one another, though such action is usually prohibited within their various pantheons. There are also gods that are the literally personifications of concepts or natural forces, such as Gaia and Ouranos, Earth and Sky.
