Infused with unified coils of deep lore shed from the writings of Lord Dunsany, Robert E. Howard, Clark Ashton Smith, Abraham Merritt and H. P. Lovecraft, Oldskull Serpent Folk is an exciting new supplement for Basic, Expert, and Advanced old school fantasy role-playing games. Herein you will find details linking the Cthulhu Mythos, the Hyborian Mythos, the World of Oldskull, pulp fiction, and world mythology into a single cohesive whole … a villainous bestiary specifically designed to deepen and enhance your game’s monstrosities and the netherworld domain. Details are found herein concerning the anthropomorphic serpent men (NPCs), humans infused with the power of ancestral serpent spirits (PCs), and naga-like eldritch horrors (inhuman monsters of considerable power). The detailed rules systems include: Viperous Metamorphosis, explaining how the serpent folk become more powerful and less sane by shedding their skin; Bond Serpents, a detailed snake familiar system for PC beast masters; the Soul Slaver caster class, being a hybrid cleric/magic-user with snake-derived and beguiling hypnotic powers; serpentine history and behavioral lore; extensive rules for special abilities, attacks, and defenses; and much more.
