It was also the only occasion on which Marvel printed a single, original, novel-length Doctor Who story. Previous efforts like Voyager and Abslom Daak — Dalek Killer were lengthy, but were comprised of several different stories, none of them original to the volume. In fact, until the publication of The Only Good Dalek in 2010, The Age of Chaos was the only example of an original graphic novel in Doctor Who comic history, despite the advertising claims seen on various collected editions of Doctor Who Magazine strips. However, it was originally intended to be published as a four-issue series in 1993 until hit by art delays.
