I can not remember the first idea here and I had started to imagine alternate histories long before that, when I had no idea of the existence of alternate histories so the first one likely must have been something about ancient Egypt, Greece or Rome.
My first tentative of writing a TL on the forum was a not too serious one as I am the first to say who its POD is not much credible and I must say who usually i do not plan too much my TLs (or if I do it, I will likely end changing a lot of things while I wrote, at least that is what happened with my first serious TL and is happening with my current ones,, who were both completely unplanned as they were both born from plotbunnies who tormented me until I started to write (like my first attempt)… Still I am always interested in so many scenarios who I will do better to not make long term plans and is not unlikely who I would end fully reworking some already partially developed scenarios in transforming them in TLs
