Greg Farshtey was the main creative force behind the largely successful BIONICLE series: editor-in-chief of the line for The LEGO Group, author of all chapter books, and principal creator of the BIONICLE world. He has since moved on to become the main creative force behind the LEGO Ninjago series.
Jolyon Yates studied graphic design and illustration at Cambridge and Exeter, and Japanese arts in Sapporo, Japan. He lived in Japan for several years, during which time he contributed comics, articles, and illustrations to magazines such as Anime FX. His first professional comics work was the story "Tancho" for Mangazine. He illustrated the award-winning web comic Revvelations, and he has been a regular contributor to G-Fan. He is very happy to be working on LEGO Ninjago but fears losing the ability to draw fingers, ears, and noses.
