Alessandro Ferrari began writing comics for Disney after he attended a script-writing course at the Accademia Disney in Milan in 2005. He's written adventures for Mickey Mouse, Frozen, Pirates of the Caribbean, Witch, and High School Musical. He also adapted numerous films to the graphic novel format, including Wall E, Up, Alice in Wonderland, Frozen, Zootopia, and Finding Dory. Finally, he's written the most recent comic adaptations of the first seven Star Wars films.

Ingo Römling was born in Frankfurt, Germany in 1969. Even before starting school, he learned to read on his father's lap with the comic book Asterix. When he first saw the magazine Heavy Metal as a teenager, he began to dream of one day being a comic book artist. But it would take a few years before that. He first worked as an illustrator, graphic designer and art director for various advertising agencies and record companies. Around 2008, he rethought his goals and joined a German team of zombie apocalypse illustrators and authors called "Die Toten" (The Dead). In 2013, in collaboration with author Peter Mennigen, he published the first volume of the successful series Malcolm Max, about a friendly ghost hunter in Victorian London. In 2014, Römling joined up with the Star Wars saga as an official Disney illustrator. He participated in the comic book adaptation of the TV series Star Wars Rebels and Star Wars Resistance on behalf of Panini. He also illustrated the comic version of the Han Solo adventure Smuggler's Run by Greg Rucka. In 2018, he met Richard Marazano and, the following year, began illustrating the series Chronicles of the Universe (Dargaud ; Europe Comics in English).
