Demideities are born when a deity forms a relationship with a mortal. They sometimes retain physical traits from their divine parents, like hair and eye colour, or personality traits, like cunning or bravery.
Demideities often have powers or knowledge associated with their deific parent's domain of control. Their abilities are never as powerful as their parents' though, but they are still powerful enough to make them superior to normal mortals.
In popular culture
- Demideities are the main focus of the films The Lightning Thief and Sea of Monsters, which are adaptions of the books by Rick Riordan.
- The Percy Jackson book series by Rick Riordan revolves around modern day Greek demideities and their struggle to live in a world full of hidden dangers. The demideities all attend a summer camp called Camp Half-Blood, run by the centaur Chiron and the god Dionysus.
