The idea behind Last Sabbath belongs to two keen RPG players, Atropo Kelevra and Valentino Sergi.

Atropo Kelevra, an ex-metal singer and drag performer, is one of the first female players of Extremelot, Italy’s largest play-by-chat RPG community.

Valentino Sergi is Officina Meningi Art Director and an award-winning game designer. The games he created include Farsight (Lightfish
Games), Xenoscape (Tin Hat Games), Rayn (Aristea), One Thousand Year Old Vampire (Narrattiva) and Brancalonia (Acheron Games - 4 Ennies Awards).

Besides, he was the Artistic Director of the team designing Blood Sword 5e (Tambù) and publishing Edgar Allan Poe - The Horror Gamebook (No Dice Unrolled Best Gamebook 2021 award), Il Sangue del barbaro and The Necronomicon Gamebook (winner of Librogames Land and Lucca Comics & Games award in 2020).

Jessica Cioffi, known as Loputyn, is a self-taught artist from Brescia, active in the Lolita fashion environment. She attended the Academy of Fine Arts in Bergamo to then follow her passion for drawing and illustration. Her artworks, published by Shockdom, include Cotton Tales (2015), Loputyn Artbook (2016), Francis (2017), and a collection of illustrations Sol (2018). In April 2019, Shockdom published the re-edition of Cotton Tales 1, followed by the previously unpublished concluding chapter of the saga Cotton Tales 2. The crowdfunding campaign for Aether, published in March 2021, was so successful that it was recognised as the Italian comic book project with the highest investment in Kickstarter history. The top six positions of the same ranking all feature Loputyn art.
