Years after the Industrial Revolution escalated into all-out warfare, Europa is controlled by tyrannical Sparks, mad scientists who rule over the hapless population with clockwork armies, bizarre inventions and unchecked power. At Transylvania Polygnostic University, frustrated student Agatha Clay seems to have nothing but bad luck. Incapable of building anything that actually works, Agatha seems destined for a lacklustre career as a lab assistant. But when the University is overthrown by the ruthless Baron Klaus Wulfenbach, Agatha is taken prisoner aboard his massive airship—and it begins to look like she might carry a spark of Mad Science after all.
