I want to know the answer to the following question:
What did the Romans do for those deities that favored Rome?
All the background I'm provided with is that "Rome offers no native creation myth, and little mythography to explain the character of its deities, their mutual relationships or their interactions with the human world, but Roman theology acknowledged that di immortales (immortal gods) ruled all realms of the heavens and earth.". Is that enough to answer the question?
Answer: no
