The Steam Engines of Oz is an Alternate Oz sci-fi steampunk comic series that is written by Sean Patrick O'Reilly, Erik Hendrix, and Yannis Roumboulias. After raising money from a Kickstarter campaign, the series made its first issue debut as a part of Free Comic Book Day 2013. The series is a semi-sequel to The Wonderful Wizard of Oz which takes place around 100 years where technology has heavily advanced. An animated film adaption was released on June 5th, 2018 as it was produced by the same company which publishes the series, Arcana Studio.


"A century after the Wicked Witch was killed, The Emerald City is ruled by a once-revered hero (Tin Woodman an ice-witch rules over the North, the Lions overrun the forests, evil twins approach from the West, and secrets hide in every shadow. Salvation for Oz comes from the unlikely wrench of young Victoria Wright, with the help of a father searching for his lost sons, a hero seeking redemption, an ill-mannered Munchkin (or three), and other friends along the way. Victoria comes to find that the smallest of actions can have much larger implications, and the most insignificant of us can change the world."
