((Okay... I'm really into Doctor Who, and I decided to take my scientist pony and start this rp. Let's have some fun with this!)) It's a dim, overcast day, but otherwise generally normal. Everypony is going about their business as usual. However, if one were to take a closer look, they would begin to notice something odd about some ponies today. Many appeared to be sick, and many others were wearing gas masks. All of these odd ponies, upon very close inspection, each had the exact same scar on their left front hoof. Suddenly, you are tackled from the side and herded into a nearby alley. Once you turn to see who dragged you here, you see that it is an anxious-looking yellow pegasus stallion with a short silver mane and tail, mechanical wings, and a mechanical right hind leg, and wearing a tattered lab coat that covered his cutie mark and cracked goggles that obscured his eyes. "Don't touch anypony." he warned, an undertone of panic in his hushed voice. You glance back at the usual marketplace crowd again, but more ponies seem to have gas masks this time. Even stranger, you hear multiple cries of "Are you my mummy? Mummy?", even from full-grown mares and stallions. You turn back to the stallion, who is staring at the eerie ponies as well.
