"The Holly Bibble: Sol Tzu, Art of CHAOS" By Wolsal
The defining literature for the Chaos cult, a remake of the original Bibble (the founding texts for DMAU). This book is written from the perspective of Solomon, and through the course you see the curtains peeled back on this unreliable narrator.
"Mini-comics" by various artists
