I have chosen to follow the story of the [Three] Golden Apple[s], with a more indepth focus on the infighting of Olympus and the Goddesses. The original story of the Golden Apple is similar to:
"During a festivity, which is the wedding of the parents of Achilles, Eris, the goddess of discord, was not invited. She got mad, so she gatecrashed the party and threw a golden apple with the inscription, "to the fairest". Three goddesses claimed the apple. These are Hera, Athena and Aphrodite. They cannot decide who the fairest of them three is, so they appointed a Trojan prince by the name of Paris to judge who is the fairest of the three goddesses
