I'm interested in writing some short fiction bits starring my Exo warlock, but even after reading hundreds of Grimoire cards I'm uncertain of many things pertaining to character development, such as do Exos eat or breathe, would a Guardian's Ghost having a unique voice and personality be possible, that sort of info. Are there any other sources of canon information, besides the Grimoire, about the races and setting you could recommend? -The Gunslick
