Helmet Totems. Speculation about what a psoglav keeps under its helmet is rampant. Some believe they keep stolen shadows and souls there, others that their helmets are part of a leash held by their breeders-and if the helmet were ever removed, one would not only see the demon's brains, but also release it from servitude to its demonic lord or summoner. Psoglav demons without a helmet are rare but extremely dangerous.
