Artemis and Apollo are twins and the children of Leta and Zeus.
Having been born first, Artemis aided her mother in the birth of her more famous brother. She and her sib then promptly killed a dragon that had come to attack them. Suffice it to say, the maturation rate of Greek gods is phenomenal!
Artemis remained an eternally young virgin whose primary interest was hunting.
Given that she was also vindictive, her prey was not always limited to game!
