Along the edges of Raccoon City lays the Arklay Mountains, a vast and heavily forested region. For the past few weeks hikers have gone missing, and the few hikers that have turned up have been found ripped apart and eaten by some kind of animal. To deal with this, the newly formed S.T.A.R.S (Special Tactics and Rescue Squad) sent out their Bravo team to investigate. When a freak storm comes out of no where and cuts off communications with Bravo the S.T.A.R.S Alfa team head out to find them and see if they can uncover what is happening to anyone who ventures into the forest. Though they manage to discover what's responsible for all of the deaths, that discovery leads them down a path of horror and pits them against a powerful and corrupt enemy.
(Note - For anyone familiar with the Resident Evil universe: Some Resident Evil characters have been replaced with ones from MLP. Plot wise this will not be an exact retelling of the games simply with ponies. There is enough different that it shouldn't be clear what's about to happen simply because you are familiar with the series.)
