Grimoirium Monstrum

From the introduction: "Within this grimoire are beasts, both ordinary and magical. Regarding F.A.T.A.L., this is a teratalogical treatsie; it is a collection, notarization, and study of creatures. Everything that MM's need to know in order to introduce monsters to their games is included in this book. When possible, beasts of fantasy have been based on mythology, not whim."
