After a young archeologist discovers an ancient tablet, a group of immortal assassins hunt him down. The Guardian stands in their way.

Yeah, I should have done that. I just threw this up here to see if people thought it was interesting. I'm thinking desert locations and historic places like The Pyramids, etc.

The Guardian was once a member of the assassins (I don't have a name for them yet). The story is that theses assassins were meant to keep the world pure, but they become power hungry and tried to destroy the world and recreate the way they wanted. The tablet is the way to achieve this. The Guardian saw this and hid the tablet where it remained hidden until Sam (the archeologist) found it. So The Guardian has to protect it.

Pretty good, my only suggestion is even more description (Ex. ancient sumerian tablet) and fit in where it takes place as that will help paint a picture as well. Also, what's the Guardian? Is he the protector of the ancient secrets?
