Not Your Hero

Korra is born into a prosperous world. A world where there are no big conflicts, a world where technology was growing. As a young child, Korra would fantasize about becoming a savior of the world, commanding respect, and turning heads. But be careful what you wish for, young Korra.
"Will I ever see you again, mom, dad?"
"Don't worry Korra, we'll always be by your side. Bye sweetie."
"Mom, what do you mean? Mom? Dad?!"

A world similar to our own (no bending and limited mention of spirits) yet more advanced than our 21st century (both politically and technologically).
Disclaimer: I do not own The Legend Of Korra. All character credits go to creators Bryan Konietzko and Michael Dante DiMartino (a special hat-tip to these two for making one of the best animated series ever).
