Mx Neon was the curator of a trans-temporal museum. They once gave River Song a tour of the Relic Room, a collection of valuable and unique items from across time and space. They gave the tour personally due to a recent staff shortage.
After also showing Professor Song a room full of prized art, Neon hired her to recover a painting, the missing sixth piece from The Seasons, from its last known location: London, (AUDIO: The Web of Time) c. 1969. (PROSE: Fear of the Web) They explained that no one under their employ was willing to take on this job.
When River could not save the painting from destruction, she decided to bring Erin Harris as an authentic period tour guide for Mx Neon. She hoped they would be pleased enough to forget about the lost art. (AUDIO: The Web of Time)
