Star Wars The Force Awakens!

There are definitely some stories to be told about the lower levels that could bring out a darker, gritty side to the shining capitol seen in the prequels.

That's kind of what I was referring to, Coruscant is a physical representation of a caste system; they continuously build upwards on top of older buildings and only the most important people are allowed to live at the top, while the bottom-most levels don't even have sunlight. Nearly every cubic meter of the entire planet is occupied by buildings that are tens of thousands of stories tall. It's definitely my favorite planet in the Star Wars universe because it has everything.
