Timeturner Tales is a serial (melo)drama that airs on the Wizarding Wireless Network in the Harry Potter universe. It was originally just an off-hand mention: my character Emily Wyke's father was a writer for the show (at Memories 1975, in March 2007). Just under a year later (February 2008), in need of a career for my character Hestia Jones's mother (at Blurred Lines), I decided to bring Timeturner Tales back, making Hestia's mother a voice actress on the show (in the role of newcomer Sitti Johnson, who ended up marrying the serial's resident aethonon breeder, Thomas Sprecher). At this point, I hadn't done up much real information on the show, but I imagine that if I'd played Hestia for longer than the couple weeks I did, I would have started writing up information on the show.
Later that year (July 2008), I was picking up Su Li at a celebrity-focused game (Life, or Something Like It), so I decided to once again bring Timeturner Tales back, casting Su in a newcomer's role. Because the game incorporated a wizards' version of television, I also devised a television-based spin-off for the show, called Port Merwyn (which is the name of the town in which the serial is set). This was the first time I actually sat down and thought about the show, and I actually made a list of the main cast of characters on the show and posted it in Su's journal.
Two and a half years later (March 2011), I once again brought Timeturner Tales back, when I wanted to play an overdramatic character who was an actor, Hugh Bradley (for Six Degrees). I cast Hugh in the role of Ryan Sprecher (son of Sitti), and took all of the information that I had created for Su's portrayal and tweaked it, expanding upon it and making some changes.
Less than a year later (December 2011), I decided to bring Timeturner Tales to yet another game (the first time that Timeturner Tales existed in two different games that I was in at the same time), with my character Pippa Dobbs (at Confundo) sort of taking some of Hestia's history: Pippa's mother was the voice actress of the character of Katherine Sprecher (due to the timeline set out in Su's and Hugh's information, Sitti wasn't around in MWPP-era anymore — or at least not old enough to be played by a MWPP-era character's parent —, so her mother-in-law was the one who married the aethonon breeder).
The latest (so far) change has been for Sidelines (January 2012). Hugh Bradley has been slightly tweaked, but he still has his role as Ryan Sprecher, and I just couldn't resist working more on tweaking some of the information on the serial. (Such as bringing the role I had originally created for Su back into the show.)
Timeturner Tales is one of my favorite pieces of personal headcanon for HP-verse games, and I've no doubt that I will continue expanding upon the information I already have, and casting characters and their family members in the serial, or putting them on the crew, every chance I get. Also, I may or may not have heavily based a good portion of the characters in the serial on characters from General Hospital, the soap I used to watch for, like, eight years.
