I'm currently trying to create a Great Kingdom army for Fields of Glory, based on the army list that Grendelwulf has posted on his blog.
The German Maximillian armor above is similar to some minis that I'd like to use for the Knights of Doom. I might do some alterations with some Procreate sculpting putty (gray stuff) and alter the helmet, either adding horns or spikes and maybe a more evil looking helm.
Do any of my Greyhawk experts have any insight into what the Knights of Doom looked like? I haven't come across any drawings in my search.
