Sentient life holds little interest for the Zoologist; he cares only for the trillions and trillions of animals that have evolved on habitable worlds. He loves everything about them, from their appearance to the way they live their lives and interact with other animals. Usually he’s content to simply observe them and let the Law of the Jungle govern whether they live or die, but he has been known to intervene when a natural disaster — or worse, the unthinking actions of sentients threaten to wipe out an animal species. Sometimes he’ll act directly to put a stop to what’s happening, but usually he just makes sure that he has a sufficient breeding population for his Galactic Zoo. This “zoo” is an entire solar system that he’s crafted with the help of Geon and the Geometer. It has dozens of planets where his goal is to keep a breeding population of every animal in existence (a goal he knows he’ll probably never succeed at, but that
doesn’t stop him from trying). His Zoo includes the only living examples of a number of extinct
Earth species, such as the dodo, the passenger pigeon, the aurochs, the wooly rhinoceros, and the
tyrannosaurus rex.
