"... and culture also isn't possible."

*buzzer* Wrong answer.

Culture is indeed possible, the very basis lies in the description of each kingdom.

If culture weren't possible, you wouldn't be able to distinguish each kingdom from each other.

There already exists minor bits of culture, but it will be up to each Kingdom leader to extend that to include stories, songs, history and other features that many cultures around the world have.
