Joseph Grabowski is the writer and co-creator of Spirits: The Soul Collector. Drawing on concepts from animism and spirit-infused storytelling, Grabowski brings emotional depth, philosophical richness, and genuine warmth to what is also a propulsive all-ages adventure. He developed the series alongside artist Colin Lor, with whom he shares both writing and world-building credits. 

Colin Lor (also credited as Colin Lawler) is the artist and co-creator of Spirits: The Soul Collector. He has worked in comic books, animation, and role-playing games throughout his career. His lush, expressive illustration style gives the spirit world of the series its distinctive visual identity — and his creature and character design has drawn widespread praise from readers and critics alike. The series ran as a featured WEBTOON for several years before its print publication.
