At Damnfx, we were originally slated to do some work on 'Solomon Kane', so the task fell to me to conceptualize the creature we were building, which was the 'Mirror Demon'. This was one of the concepts, which is much more colorful and gelatinous than they eventually became. Originally, there was a call to have a lot more subsurface scattering and the indication of a diseased mass within, held in place with a gelatinous substance. floating within is a skeleton, which was to be used to block light from passing through.
The final tests had promise, but, Damnfx did not complete the contract.
