Nephandi Groups

Book of Madness pg. 14-15 lists:

• Outsiders - Serve Deep Umbral unknowable beings
• Infernalists - Serve demons, the Devil
• Malfeans - Serve the Wyrm of Werewolf lore
• K’llasshaa - A group of insane, unpredictable Nephandi that are Outsiders, Malfeans or both

Book of Madness pg. 15 claims Infernalists are most numerous, Outsiders are least numerous, Malfeans have best understanding of Entropy Sphere.

By the time of Book of Mirrors (pg. 82) the the K'llasshaa represent all Outsiders so there are only 3 groups. The Benevolent Society of Lost Souls is a social club where Nephandi from the 3 groups socialize & work together to kidnap victims. Book of Madness Revised has the 3 groups from Book of Mirrors.
