Paul Magrs created the character of Iris Wildthyme for his Phoenix Court series of novels (predating this, an earlier version of the character appeared in his first published work, Patient Iris).
She was first introduced to the Doctor Who universe in his 1998 Fourth Doctor short story Old Flames before being more fully featured in several novels of BBC Books Eighth Doctor and Past Doctor ranges.
Iris later made her audio debut in Big Finish Productions' Excelis Dawns, where she was portrayed by Katy Manning. Manning would go on to play Iris in all future audio stories, and she would be the basis for illustrations of Iris on the cover of most Iris Wildthyme books.
In August 2005, Big Finish released the prose anthology Wildthyme on Top as part of their New Worlds label. This was followed a few months later by Wildthyme at Large, the first Iris Wildthyme audio story, which notably introduced her companion Panda. Further anthologies of short stories and novellas featuring Iris were published by Obverse Books, (as well Salt Publishing) and Paul Magrs wrote further novels featuring Iris and Panda for Snowbooks Ltd.
