1. Gods do not sleep since they do not need to. If they do it usually is out of boredom to pass the time.
2. Gods are powerless in other gods' realms. Example: Ares wouldn't be able to use his abilities or powers if he was in Poseidon's realm where he ruled underwater. Poseidon would have no powers or use his abilities in the Underwold which is Hades' domain.
3. Gods do not destroy or desecrate other gods' temples. Its just something that they do not do.
4. When a gods name is spoken they can hear it. When invoked they can appear where they are being called to.
