Cullen grew up in rural North Carolina, but now lives in the St. Louis area with his wife Cindy and his son Jackson. His noir/horror comic (and first collaboration with Brian Hurtt), The Damned, was published in 2007 by Oni Press. The follow-up, The Damned: Prodigal Sons, was released in 2008.

In addition to The Sixth Gun, his current projects include Crooked Hills, a middle reader horror prose series from Evileye Books; The Tooth, an original graphic novel from Oni Press; and various work for Marvel and DC. Somewhere along the way, Cullen founded Undaunted Press and edited the critically acclaimed small press horror magazine, Whispers from the Shattered Forum.

All writers must pay their dues, and Cullen has worked various odd jobs, including Alien Autopsy Specialist, Rodeo Clown, Professional Wrestler Manager, and Sasquatch Wrangler. And, yes, he has fought for his life against mountain lions and he did perform on stage as the World's Youngest Hypnotist. Buy him a drink sometime, and he'll tell you all about it.

Cat Farris is a native Portlander, an artist, and pretty sure she's just making this up as she goes along. She is supported in this venture by the world's most beautiful husband, the laziest greyhound, and an all-star cast of Helioscope studio mates. She has done art for various comics publishers, including Oni Press, Dark Horse Comics, and IDW Publishing.
