This is the Inquisitor. He is the embodiment of those who judge art wrongly, those who are not ready for art to evolve into something new. The Inquisitor represents moralists and conservatives from different ages, religions and political beliefs, it doesn’t matter, they’re all the same.
His job is to hunt and kill every artwork creator and guardian in the world, and to burn all their inovative creations.
He killed the first guardian and carries his helmet at all times.
