Original Description:
 
Below, three of those robots were rolling about, looking for me. They were tracked things, built to somewhat resemble ponies, with clear domed heads that housed real brains. I refused to think that the ponies who built them might have used other ponies’ brains in the construction. The thought was just too horrible. Even doing that to an animal’s brain was awful. And clearly, two-hundred years of continuous operation had done nothing for their sanity.
