Brain storming for Rp storylines

[Titrin]

I'm not sure this belongs here but I had an idea for an Rp topic but i needed a serious tune up on it's stroy line, so i have come here to ask for your help on this improvement.

My story line so far:*
Storyline: A Rift in time has appeared in three distinct eras.
a Dark-age Era: which beleives in Magic, Vampires, Demons, but also Has knights and kings.
A current times Era: which uses technology of the current to battle, dispises all magic and has no honor, it is full of theives.
And A Future Time period: This era is mking use of all it's deadly technology to do battle against any foe, magic or not. It is full to the brim with high-tech assasins and genetically altered feinds.
To start you choose your time period and what your power's will be no one can choose two time periods, and no one from one age can steall the tech of another, stay with your own weapons and armor.

*please note that this storyline was from when i first started rping.

I bring this before you to be critizised but not needlessly, I.E. i want help nothing like : "boy that sucks,XP"
