I am certainly keeping the main plot SPN. The plan is to leak a little bit of Doctor Who inside by dropping some aliens who slip through the cracks. They will still be weakened by the travel, and able to be captured, and ect.
An idea that I would like input on is: What is Purgatory?
Personally, I never felt it was a place on earth, but that can be argued. I was wondering about making it another dimension? It's still SPN based, but can play a little more sense with the Doctor Who folks. If this doesn't sound like a very good idea, we can just keep it a seperate place 'somewhere' in the universe, like Heaven and Hell are.
Also, the Alphas and Eve will produce a certain energy that isn't human, because they're from Purgatory. Just as the demons will produce a certain energy that isn't from earth, because they're from Hell, just as angels will produce a certain energy because they are from Heaven. The Purgatory energy is something that Torchwood has learned how to locate, but they will not be aware that it isn't actually Purgatory, but Eve's energy instead. They will actually have to get their hands on a demon or angel to start to figure out how to trace that energy. If this is not okay with anyone, please let me know your ideas. (and if we end up having Leviathan running around, they'll have their own different energy.)
Anything Eve creates will have her energy, and will be trackable unless Torchwood tech is damaged or destroyed.
Let me know how that sounds, and this is going to be way down the road. Currently, the two Alpha in game are being hunted for, and I already have one person who has spoken to me about making a dragon. It would be nice to get at least one or two more, besides the Mod account.
Thank you all for your input!
