((THIS IS NOT A 'THE WALKING DEAD' CROSSOVER, BUT IT IS SIMILAR))

It came so fast.

Nopony knows what caused it, or in the horrifying thought, who.

All they know is that they have to survive.

But friendship is shattered and trust is tried as Twilight Sparkle struggles to make her way to the ruined city of Canterlot while dodging the hungry mouths of the undead that follow her and anything else left alive.

But Twilight has more problems on her mind than just the undead, such as why can't she remember when this all started?
