This place is where the Diamonds live. It is called Big Fall City because it is best seen during Autumn, but it is also called Big Fall City because it keeps falling from the attacks (meaning they get attacked often and the attacks are big). The Diamonds live in a tower that is a shape of a D (if you watched teen titans the tower almost looks like that but instead of a T it's a D).

The place is a little cold which makes it nice for the people living there except for Elisha she wears long sleeves almost everyday, she even wears long sleeves when the temperature is 30 degrees she is very thin which makes her get cold easily.
