Avatar Korra's rule had been an eventful one, and while she may have never faced a single threat as terrible as the Firelord's armies, she struggled with more particular crises than possibly any single avatar before her.  In her 91 years, she oversaw the restoration of the Air temples and was instrumental in bringing the Air Nation back into the world and defending the vulnerable, fledgling nation.  Several of her years after defeating Kuvira were spent in Republic city however, as the struggles there never entirely seemed to cease.  While Korra had dealt with most of the city's serious external threats relatively early in her life, there always seemed to be a new political disagreement that required her attention.  She tired of this quickly, and moreover citizens were beginning to complain that the Avatar was far too valuable as a political prop, and that any issue she lent her name to was bound to have an unfair advantage.  Once again, president Raiko was forced to ask Korra to leave Republic City, and she agreed, this time for good.  For 77 years, Republic City got along well without an Avatar.  

The product of those 77 years is where you find yourself, for some reason or another.  It is late afternoon, the city's factories are just shutting down and the local shops and restaurants are experiencing their busy hour.  In the business district a slight, well-dressed woman with ill-fitting cuffs, recognizable to most as President Kanna, is proudly addressing a crowd about the opening of Republic City's first triple-decker street.
