My Little Foundation: Containment is Magic

When a pony is trapped in the SCP Foundation as personnel D-9341, all the ponies he once knew and once loved in Ponyville, are now SCPs subjects that would kill any living thing. Now, D-9341 is hunted by those murderous ponies as he is trying to find a way to escape from the containment breach, and discover the darkest secrets of SCP. Based upon the mod of "SCP Containment Breach."
