Seige of the Cyberponies

Derpy is an ordinary pony. Well, as normal as a pony with wonky eyes can be. So when a stallion offers to take her exploring, she doesn't even hesitate to leave her boring life behind. They travel years into to the future, hoping to see a glimpse of what Ponyville is then. What she sees though, she was not expecting, not at all.

She just doesn't know what went wrong.
