Matter of factly, my character itself doesn't have a visible form. The thing that you/your characters see upon laying eyes on him is the absence of light on that area and not my character itself. And the swirling mass of shadows as it is viewed by your characters is a result of their inability to properly comprehend his true higher dimensional form which passes and extends in more directions than observable by simple humans or even simple spirits.
