From the introduction of the product: Knowing there were a lot of fans out there who’d like to incorporate Ptolus into their Arcana Evolved games, I was thrilled when Council of Magisters member Søren Thustrup volunteered to draft a conversion document to help players accomplish that very thing. His end result gives DMs exactly what they need, including both general advice and specific content. I’ve been mixing elements of Arcana Evolved into my Ptolus Campaign for years, so I know it can be a fun and rewarding experience. Thanks, Søren. — Monte
