Everypony knows how the Caribou first came to Equestria and how effortlessly they invaded, twisted and claimed it for themselves. Following a year of their successful conquest and enslavement of the nation’s denizens, as well as its neighbours, the Caribou prepare themselves for the festivities to commemorate the occasion.

But there is one question that nobody seems to be asking: why?

Why come to Equestria?

Why abandon their homeland?

Why barricade themselves within Equestria’s borders?

Are they trying to keep themselves and their conquest in?

Or are they trying to keep something out?

Days before the festival’s beginning, a storm builds beyond the borders of Equestria, bringing two things in its wake: a dark cloaked stranger, and retribution.
