With the re-enactment of the founding of Equestria under way, Rainbow Dash unknowingly takes her role as commander hurricane too seriously, unlocking an ancient pact that the windigos had made with commander hurricane himself. Rainbow's wish for companionship right then had forced a windigo adolescent foal to take the form of a pony, but with his memories erased.

Now with a pony that insists on calling her Commander Hurricane and insists on following and doing everything for her, Rainbow Dash has to find a way to adapt to her new lifestyle and tolerate this new pony, or to find a way to send him back to where he came from.

Story contains windigo OCs. Not a fan of OCs? Don't hate and just disappear, please.
Also... Somepony really should create a windigo tag
