The people of Nakti interact with animals in many different ways. Some creatures have lives that are intimately entwined with people's while others grudgingly occupies the same place and little more. Whatever their nature, these relationships may shed light on a culture and the organisms that surround it.
The four-group system
There are four main categories that a people-animal relationship may fall into, each with 3-4 subcategories. It's worth noting that an animal may fall into more than one category, or in different categories for different cultures.
The first group consist of animals who get along badly with people for one reason or another. Note that direct hostility is only one category, and in real-life, a fairly uncommon one.
These animals actively hunt people, maybe not as their primary target, but often enough to make them a threat. This is a category that is more common in myth and fantasy stories than in real life.
These animals do not actively hunt people, unless they are starving. But they are dangerous if disturbed or provoked. The main rule of dealing with these is “you leave them alone, they leave you alone.”
These animals do not attack people directly, but they to wreck havoc on crops or livestock, anything people depend on to survive. These do not have to be predators, as any gardener with a deer problem can attest to.
These animals aren't actively a problem in any way, but they are an inconvenience. They live among people without their consent and while a singular individual is mostly harmless, they need to be kept in check, lest they become too numerous.
The second group consist of animals who live in the wild and can be put to use in some way, often but not necessarily as food.
These animals can be hunted as a welcome protein supplement. They are usually herbivores and may be cute.
These animals aren't important in and of themselves, but they are helpful to people trying to navigate the wilderness. Maybe their behavior marks seasons, maybe they make paths to the nearest watering hole. Maybe they just prove a specific area is relatively safe by their calls. Whatever the reason, a savvy survivalist knows to look out for them.
These animals aren't important for survival, but they are pretty and more leisurely individuals might take up collecting them, or a byproduct of them (pearls for example.)
The third category consist of animals who have been domesticated and actively live among people. Their history is intimately entwined with the people they are associated with to the point where they are basically inseparable.
These animals are bred for its utility, as a source of meat or to harvest a byproduct from them (milk for example).
These animals can navigate distances and carry burdens people can't handle on their own. They may be ridden or used to drive a cart.
These animals are friendly and are bred as pets. They may be used to hunt or to herd animals, or simply as a “man's best friend.”
These animals aren't much in terms of companion, but they are kept around as living decorations, be it in an aquarium, free-roaming or a cage. They can often be bred for variety, including different colors or body types.
The fourth category consist of animals that jog peoples imagination in some way. They may not actively interact with these animals, but they nevertheless shape how people see the world.
4.1. Bad omens
These animals are feared and shunned, possibly for good reason. They may prefer the dark, or feast on the dead, or just be shrouded with a sinister reputation. They may be seen as a sign of bad luck, or be associated with dark magic or other taboos.
4.2. Good omens
These animals are celebrated and welcome, possibly seen as nature spirits or guardians. They may be associated with good luck or with benevolent deities.
These animals figure in stories and metaphors, arts and craft. They may be assigned a specific meaning, be associated with a certain attribute, or just be a common motif. Sometimes the symbols they helped inspire are so stylized you can't see the connection right away.
It is very common for world builders to create only hostile animals, and the cumulative effect of this is a world that becomes almost comically deadly. In order to give the world a sense of having a vibrant fauna, there should be at least some animals in each category. These can be fleshed out when creating a culture and deciding what their relationship with nature is.
