Okay I have alot of ideas but that is my problem, so I have chosen to pick one and stick with it. Here we go ...
Anatomy
The bulk of the plot will be romance; but whether or not it develops and at what speed is up to you (the female lead) to decide. I like a fictitious setting for my plots but I am not against real world locals (future or other wise). There will be a world ending event that your character will be directly involved in stopping as well as a variety of NPCs to interact with.
Intro
When a snake bits. It is not the bit that kills but the venom. And just like a snake when Lucifer rouse against The Almighty it was not the war he expected to win. Lucifer just needed to remove God from the equation. Even after 100,000 years of punishment Lucifers influence spread across the Angelicas ranks until eventually they had enough strength collectively to imprison God and invade Hell. While Death squabbled with itself and the Fates did nothing only one power remained to stand against Lucifers hatred. Gaia, Mother Earth. She is the boundary between all dimensions but against both the armies of Heaven and Hell she will need her own army and a Champion to lead it.
Plot
You live in a small village/town that has been under attacks from demonic beings. Because of the small population of your village/town and it's insignificant economic standing in the world your suffering has gone unnoticed by the Holy Knights but your Mayor has managed to peek the interest in a warm blooded Mercenary with a small fee. The Mercenary is expected to arrive any day now.
Your Character
The only thing I have to say really is she owns a B&B or Bar in the town/village. It is where our characters will meet and the story will begin.
Any questions or ideas you would like to share please do not hesitate to respond.
