An odd man-like shadow-creature to which fades in and out of dimensions, it's often very disconnected as a result.
Being a dimensional traveler has it's effect on ones perspective, it is best describe it as disconnected, he will often converse with himself or ones who you cannot see. It is for the most part highly benign and uninvolving.
It doesnt appear to be wearing or holding or carrying anything, most of the time.
This person, if you like to call it that, has no history in this dimension. It will bring up odd places and events and names and races in conversation but often it makes no sense and or is false for this dimension's entities.
