Diana is an original character created by artist huffslove for the Tome of Imps series. Originally a human adventurer, she discovered the Tome of Imps in a dungeon during the first comic to feature her, and was slowly turned into an imp as well due to the magical influence of the book. She's now just one of many imps inhabiting the Tome, and appears in other comics and 1-shots as well. She was a good friend of Amy before her adventure, and mailed the Tome to her after turning into an imp.
