Have you ever thought how weak your body is? Your skin can be cut, your bones can be broken. Would you like to get rid of these flaws? Would you replace something fragile like your legs with something unbreakable and durable?
Most of you have already thought about that, haven't you? You know, there is always a choice… Isn't it?
What would happen, dear ponies, if you were forced to become somepony you never wanted to be? What if some crazy scientist kidnapped you and experimented on you?
That's what happened to a stallion named Moonbeam. He was put out of his peaceful life and put in a lab to be the subject of scientist's experiments.
That is probably the last thing you wanted to become, right? But Moonbeam, that poor stallion, never had to make a choice. But now he escaped, completely lost and forgotten, alone in the whole world, and completely without any memory of what happened to him. And he is a target for who are after him.

Will the poor stallion live long enough to return his peaceful life back? Or will he be put back in his sterile prison where the crazy scientist is waiting for him to continue the experiments?

Wish Moonbeam good luck, for he needs it more than anypony else.
