I think calling the perpetrator an "artist" is probably stretching it. Each of the Conspiracy archetypes looks to be his work, judging by the 'artistic' splatter of ink over each. At best they appear to be collages (if you can call sticking a head on another body a collage); the illustration for Ascended Ones looks like another total trace job, if from some magazine rather than an artwork.

I hope his name gets passed around the other rpg companies, so they know better than to trust this individual again.
