Morrie Mullins was the Campaign Designer and Plot Director for the Living Force RPGA campaign for Star Wars: Roleplaying Game at the campaign's beginning. He co-wrote the Living Force Campaign Guide with Robert Wiese, but for contractual reasons did not receive authorship credit. He wrote many adventures and online supplements for the campaign. He eventually stopped being the Plot Director, but continued to write many Living Force adventures and all the adventure supplements (other supplements which were not associated with specific adventures were rules updates written by August and Cynthia Hahn). He also wrote several of the the Planet Hoppers series of articles, which were eventually taken over by Cory J. Herndon.
