More than seven hundred years ago, a man with no memories and unprecedented magical power was found near the construction site of a great bridge – a spanner tenganden. Wandering through lonely centuries without purpose and yearning for an ordinary life, he finds direction in the Elbestran Colonies, a land of settlers struggling under the rule of a tyrannical archduke. In the Elbestran Colonies, Spanner Tenganden may, at last, find a place he can call home forever. But when Spanner and his friends engineer a revolution for independence, he discovers that powerful wizards have conspired against him for centuries. Driven by a prophecy that predicted catastrophe at his hands should his life ever find meaning, wizards have worked tirelessly to keep Spanner’s life in obscurity.
