Hephaestus

Divine Soul - this part represent their memories, emotion, wisdom and anything that makes them become them.

Priesthood/Domain - this part is the thing that makes them become gods. Priesthood are given by the world and are the ticket to be called a god. Anyone that doesn't have a priesthood can't be called a god. A god can only have one priesthood. They might have the authority of other laws but they can only have one priesthood.

It does have to be noted that a god can only go to the rank of great god if they collect all the authorities of their respective laws. Like Posieden, he was unable to go to the rank of great god due to some of the authority of the sea being with Oceanus and Tethys. But after Oceanus and Tethys scattered their priesthood, Posieden manage to finally get all the sea authority inthe world and intergrate them into his sea priesthood. Giving him the chance to become a great god.

Divine Personality - This part represent their achievement like Helios achievement in making the sun give birth to fire. This is also the place where the authorities of other laws are stored. For example, Helios's fire authority is stored in his divine personality due to fire not being his oriesthood thus cannot be fuse with it. Gods can devour another gods divine personality to take their achievement for themself and get the authority gain from that achievement.

Divine Body - the divine body is the body of a god. To own a divine body, you have to become a god because when a being gains a priesthood, the world will bath their bodies in the laws of the world which granted their body the characteristic of a god like the ability to never grow old, the ability to condence divine power, etc. It does have to be noted that divine power is the energy gods use if they want to do something that they don't have the domain to. For example, divine power is the thing that lets gods transform into animals even if they don't any authority or own a priesthood related with said animal.
