In 1.4 patch this faction was renamed to "Monsters".
The Nature faction consists of all the wild beasts that are native to Ardania and its alternate planes. They are hostile to all Great Mages as well as to the Neutral faction. They have the ability to take over any city if they attack them and get the city low enough, just like any player can. They can be identified by a brown color code.
These monsters, aside from the ones that appear in the world at the start of the game, periodically spawn from nests that are specific to one, or multiple types of beast. These nests can be looted by moving a unit into their hex. Depending on the type of nest, this may give you a generous amount of gold, mana, or both. There is also a small chance that it grants you a unit from the nest for you to control, or an Arcane spell that has not yet been researched.
Many types of nests and the monsters they spawn can only be found on other planes, such as Dragon Nests and Elemental Portals.
The types of monster nests and their rewards are listed below.
