The 4th issue is focused on demons and demonologists. It contains the expected mix of character classes, creatures, an NPC, spells, setting information, and reference lists.
Unlike the previous three issues, which for a good part collected material from various sources, there's a lot more content originally created for the fanzine in this issue.
