Well, I figure I'll go ahead and spoil the story I have planned now, because really, I need help with this whole time travel things.
In my story, a character named Neville Morgan attemps to see what sort of effect a mass time-travel device has on its surroundings, and it catches him in the wake. He is shot back in time (supposedly) into 1500's Arabia. (spoilers follow) The problem I have is, for my story to work, the device doesn't take Neville back in time, like a Time Turner would, but takes him into a different world that takes the form of 1500's Arabia. The reason I need it to be a different world is two reasons:
a) in a different world, Neville's wand is impotent (shut up) and unable to channel magic, forcing him to stick with Alta´r because Alta´r *can* use magic
[massive plot spoiler below]
b) towards the end of the story, it is revealed that Alta´r and Neville aren't two different people, but one person, divided over two worlds. So, Neville is 2008-era Britain-world person, and Alta´r is 1500-era Arabia-world person. Yeah, it's confusing, I know. Sorry.
The real reason I'm asking this is because I need help developing the idea. Does it work? I know it needs massive amounts of tweaking, but I don't want the story to have the same odd ending that PA did.
