The Queen's Heir
Zeus cheats and cheats and cheats. Olympus is full of his offspring, like Apollo, Artemis, Dionysus, Hermes, Athena, and more. Hera was angry, understandably, after centuries of cheating. One day she had enough, and cheated, just once, on him.
Just her luck, that a child would come from this cheating. After fighting with Zeus, the child was allowed to live on Olympus with the other gods. After all, Zeus's offspring from flings were allowed on Olympus, why couldn't hers?
You are this child, a young godling. Your mother, Hera, positively adores you. Zeus doesn't like you, but the other gods are intrigued and interested with you, curious about their new housemate.
