Twilight was the first pony ever to create an android she called Ultron. It was built as the ultimate aid in household chores. Based off of the plans given to her by Lyra, its humanoid body is best suited for such activities. When she gave it an A.I with the ability to adapt and learn, she believed it would become more useful for other things besides common house chores. What she didn't expect was its ability to feel emotions, more specifically a hate for pony's. This hate drove it to believe in a need for conquest and annihilation of every living thing in equestria.

Twilight Sparkle has prolonged a visit to the ponyville grave yard for far to long, things need to be said and long suppressed guilt's need to be relinquished.
