And thus the first Twilight vampire was born. In a blind rage Applejack killed Pinkie Pie. When Twilight Sparkle tried to subdue her Applejack killed her as well but was trapped in a barn with Pinkie Pie and Twilight's corpses when she tore it down. With nothing else for substance and still in exrutiating pain from the glitter in her eyes, Applejack began drinking the blood of her dead friends for nourishment, the act of cannibalism drawing the Wendigos back to Equestria. They froze her in her blind, bloodthirsty state, and Celestia's last act before leading another mass exodus from Equestria to a new, not frozen over continent was banishing Applejack to a human world.
