On her latest administrative mission, Princess Twilight Sparkle and her entourage of friends are off to the frozen north-western reaches of Equestria.
There, in the icy cold over three centuries before, Princess Celestia established a small colony as a base for the future settlement of the region. The purpose was to spread the ever increasing numbers of citizens out over a wider area and avoid over-population. It is a similar idea to Appleloosa's and even Ponyville's founding.
The difference though is that this colony, Koltsovo as it's known, was Equestria's first and most dreaded penal colony. Though there are few such colonies of Equestrian criminals, this one has been the bane of Celestia for her to allow admittance, seeming resistant to being admitted into the kingdom. Now this developed, populous and, as they call it, 'industrial' land may at long last be ready.
