The year is 1900 and 13-year-old Lumen, raised in the peaceful Indian countryside, cannot imagine the thrilling changes her life will begin having as she ventures forth into this new and thrilling century.

Lumen’s new existence in a world of retro science fiction begins when her home is attacked by steampunk assassins. She is then shocked to learn her family lineage upon meeting her grandfather, the legendary Captain Nemo; central protagonist of Jules Verne’s classic novel 20,000 League Under the Sea. However, Lumen must quickly accept this and learn to work alongside Nemo if they hope to save the world from a cadre of evil masterminds, bent on seizing control the world.

To that end, Lumen and Nemo’s first foe is none other than another Verne creation, the villainously insane but almost unstoppable Robur the Conqueror, whose goal is Paris’ destruction.

Lumen’s first incredible arc introduces us to a young girl, eager to do right, who will evolve adventure-by-exploit into a fearless and unique steampunk champion.
