Embittered time traveler Arthur Koenig finds himself stranded on a parallel Earth. With his time machine destroyed, he scours this strange new world for the rare elements that will enable him to rebuild his machine and set the timeline straight.

However, he is not the protagonist of this story.

Embark on an adventure in a dieselpunk-inspired version of 1950, where the fiery Sandra Lockhart, captain of a rogue zeppelin and its ragtag crew, is on a race to uncover an incredible secret buried in their world’s past. They must elude a mysterious dictator, seemingly hell-bent on the destruction and subjugation of the entire planet, as he scours the world in a merciless campaign of terror, with machines of war unlike anything seen before. Why is this dictator ravaging the Earth? Why is he so interested in recent archeological finds in Central America and Northern Africa? And most importantly of all, what will happen if he finds what he’s looking for?

Sandra Lockhart and crew intend to find out.
