Eric Steinberg, now reincarnated as Elliott Roosevelt, lives many lives under different names. To some, he is Frankenstein, the brilliant inventor rumored to be part of the ancient clockwork race—sentient beings of metal and gears, revered as gods of machinery. To the aristocrats, he is The Professor, a scholar whose revolutionary ideas shape their world. As X, he is a shadowy villain sworn to dismantle the council's oppressive rule, believed to be descended from a powerful mage. And as Runakhor, he is the lost son of the emperor, the eleventh prince of the Emanthil Empire, and a possible contender for the throne. But to Audwin, his younger brother, Elliott is simply "Elli"—the protective sibling who would burn the world down to keep him safe.
