Cylinder Block hates dealing with ponies, but in order to achieve certain things he has to. Being a simple scavenger and a craftpony, he enjoys working with machines more, because they never complain and are generally quiet. He is perfectionist, he likes to work on things to every detail, fixing even the smaller things.

Living futher away from the trader town in a small cellar which he alone rebuilt for himself only, he enjoys his privacy and the silence.

The legend says that somewhere under the city is hidden a laboratory, thriving with technology, holding long lost secrets of machinery development. Of course our main hero is trying to find it and use it to build more complex and more useful machines for ponies to use.

The town is littered by urban legends and stories, unfortunately no one knows where is the border between a story and the real wasteland life.

His silent and calm life changes when a mare keeps following him, and eventually making a deal to trade off her information she gathered about this legend, for his company.
