"Biology" is the study of life in the multiverse, in any or all of its myriad forms. Although there is frequent disagreement among biomancers over the precise definition of "life", the field is generally agreed to encompass not only the study of evolved, self-replicating organisms, but also other types of emergent, spatiotemporally localized processes including undeath, elemental manifestation, anthropomorphic personification, and intelligent design.
