One Origin Story of Olympus and the Felines
Vesta, the Roman goddess of the Hearth and Welcoming (among other things) is at the heart of the creation of the Felines. Vesta grew tired of the elitism and small size of the inner-circle of the 12 gods seated on Mt. Olympus. When their temples on earth were falling and it was clear that the humans they created would no longer worship them, Vesta decided it was time for a new creation. She desired an Olympus to parallel their own, as the humans they made were too feeble and were ultimately a disappointment to the gods. She would make a countless number of these parallel gods, and they would be practically immortal. They would not reproduce sexually, but they would be able to create more of themselves. The gods liked the idea of a new race, but were uncertain of making them so powerful and in so great a number, for fear they might rise up against them. Vesta smiles- there is no access from our world to theirs- we only have the power to create it and then view it. Felines are generally uninterested in their own origin: they are constantly looking ahead. They can form powerful bonds, but other short term friendships or alliances/incidents/minor violences may be totally forgotten. And so the Feline Olympus was created and left to its devices.
