The Ninth RayEdit

The Ninth Ray is a mysterious energy that appears as both a blue glow or as tendrils of light when it is being utilized or manipulated.  It is a major plot point of the movie. It was mostly used by the Therns but Dejah Thoris was close to unlocking it's secrets. The Therns can manipulate the Ninth Ray in a variety of ways, such as solidifying it to make simple constructs such a blades, allow them to levitate, control someone's body or use it as a beam that can disintegrate someone on contact.
