Green Knight Publishing was founded by Peter Corless in 1998. He had acquired the rights to Chaosium's award-winning Pendragon role-playing game after they defaulted on a loan from Corless with Pendragon as collateral.^[1] From 1999 to 2001, Green Knight published supplements for the role-playing game, in which players take on the roles of knights and ladies performing chivalric deeds in Arthurian Britain. Under the direction of executive editor James Lowder and consulting editor Raymond H. Thompson, Green Knight also continued the Pendragon fiction series, which offered reprints of "lost" classics of Arthurian fiction, as well as original novels and anthologies. The company sold the rights to the Pendragon RPG to White Wolf, Inc. in 2004.^[2]
