Way back in day, the core book of Exalted, First Edition introduced the "spine chain". This is a nectrotech monstrosity created by cutting bodies in half, and shoving the head of one into the torso of another end to end in a long "centipede of evil". Ever since hearing of this idea, it's bugged me that this is sort of wasteful. What about the legs? What happens to them?
So, Necromancy McEvilpants just built a 20 section spine chain, leaving his assistant to "clean up the mess". As his assistant, you are an ambitious necromancer yourself. You have 20 lower body halves, from the waist down. What do you build with them? (You may assume epic-fantasy-level magic if you like, but you don't need it.)
