This would be a novel telling a tale about a war between mages and vampires. 

There would be some creative license so that vampires are "even" to mages, what is not true according to some RPG materials, or so I've heard. I really don't know much about it.

I worked on it for a while, deriving a lot of ideas from a computer game called Age of Wonders. There would be mage towers, and the vampires so threatening because they discovered a fallen asteroid, crimson in color, and incorporated it to its blood magic. 

That is what I can remember, lol. I really couldn't get past choosing character names. Anyway, have fun.
