Animals and Creatures
A billion years in the future, all the animals we know in the 21st century are long gone. However, animal types—mammals, reptiles, insects, birds, and so forth—remain. Again, it’s a language problem. The text (or the GM) might talk about rats, deer, flies, or ravens, but the beasts being described are at least slightly different than the creatures we think of today. However, the words are still valid because they convey the proper general meaning. Wholly different creatures, such as aneen or snow lopers, are described because they have no 21st-century analog.
Of course, the Ninth World also has creatures that are nothing like animals. Mutant beasts, engineered creatures (or their descendants), automatons, biomechanical blends of organism and machine, extraterrestrial and ultraterrestrial beings, creatures of energy, and stranger entities roam the planet. In one way or another, all of these things are results of the influence of the numenera.
