Zack Loran Clark and Nick Eliopulos are best friends with a shared love of role-playing games, epic fantasy, and spooky stories. Together, they are the authors of The Adventurers Guild trilogy. Separately, Zack is the author of The Lock-Eater, and Nick has written more than a dozen officially licensed Minecraft books. Zack lives in Brooklyn, where he keeps a collection of potentially mystical artifacts. Nick lives in Upstate New York, beside an allegedly haunted river. Thanks to the wonders of the Internet, they still game together every week.
