From the front matter:
Within these pages you will find adventures, monsters, magical items, and spells around the theme of the school of vivimancy: the study of bio-sorcery. Much of the content can be dropped into any campaign without the need for further material, however reference is sometimes made to the vivimancer class, a magic-user sub-class specialising in flesh-warping, genetic meddling, neural manipulation, and vat growth. This class was first presented in a basic form, in Theorems & Thaumaturgy. The later The Complete Vivimancer greatly expands on vivimantic magic and is the ideal companion to the new content presented in this book.
