Well, none of my plots have to really do with vampires. But I am already doing a role play with that sort of plot. Are you a fan of Hellboy by any chance?
And here are my plots that I have for now:
-A slightly insane young man/woman who finds himself in the middle of a crossfire between two gangs, ends up hurt and taken in by a gangster of either side.
-A dragoniod pair are thrown into a absolute war against a rival clan. These two have grown up for their entire lives side by side. It takes place very early in history, maybe early medieval times.
-(A mulan type of story). A girl lived most of her life dressing up as a boy. She was forced to by her father. He wanted a son. It's rare ever to see her in a dress. She left home when she was 18 so that she could figure out what she was going to do with her life. On the way she got caught up in a war. As you can see, I have not really thought this one out too much.
-A Renaissance artist is accused of murdering his/her brother. The only problem is, the real killer has hired an assassin to kill the artist. Not only does the Artist not know his/her brother is dead, but he/she has an assassin on his tale.
-Welcome to LA, where things tend to go bump in the night. This pair works for the Bureau for Paranormal Research and Defense. Pretty much a Hellboy type of plot if you did not get the reference.
