@ShadowRaeper: Of course they would be noobs. :D What's the fun of not having to learn everything?

As for the specific threat, I'm thinking supernatural creatures that are tired of having to hide away in fear of the humans. So vampires, werewolves, malignant spirits, etc. would comprise the alliance against the humans. Exact races can be determined later, and I am open to all suggestions as to which should be included. :3

I'm really glad that everyone is so excited! It seems like this will be a lot of fun. :D
