Those are some good looking models. Where/how did you get the files?
Thank you for the kind words. The files in question come from here. They are actually in two sets. https://gamedecor.com/dungeonworks.html Total of $7 spent. The death knight set was less of a bargain as it only came with 3 versions of death knights. The skeletal mage came in a set with several other useful models.
