This is a character named in the credits for IWHS. I’m guessing he must be one of the Ostral-B Heretics helping Thodin, but if anybody has a definite answer, that would be great.
I think that it may have been the poor unfortunate heretic that became a Cluster Lizard snack.
This may or may not be Gil Brenton who was in a Troma film called “Nuke’em high”.
