Funny, but my ideas just seem to come out of nowhere. So far, I have written two stories involving the Romanov's.
1. I have a series of stories called the Rex and Hannah Chronicles, it's a spin-off of the TV series Charmed. For my 13th R&H story, that I titled Requiem, I came up with the idea of Rex and Hannah encountering the spirits of NAOTMAA, who have been Earthbound since their murder in 1918. As the story unfolds, Rex and Hannah must find out why the Romanov's have not crossed over (this story also has some Ghost Whisperer concepts in it too).
2. The second story I wrote, Bid Time Return, started off as part of the Alternate Ending For the Romanov's thread. My idea, that just seconds before their execution, the IF is rescued and taken to the 29th Century. This was originally supposed to be a one off thing, but I found myself adding further chapters, it just kept going and going. So I gave it its own thread and title, Bid Time Return (in fact, I may try to get this one published).
Of course, this is not counting the soap opera thing that Romanov History Buff, myself, and others are writing.
So I may come up with future ideas, who knows
