Xenogenesis in Fantasy Settings

This fantasy roleplaying supplement explores xenogenesis, in which one species gives rise to another. It presents four forms of manufactured creatures: Will, Alchemy, Natural Laws, and Blood Auras. The book provides guidelines for creating and incorporating these creatures into games, along with statistics for 27 sample monsters. The material is written for the Basic OGL/d20 system and can be adapted to other games using similar core rules.
