World Building: Humans
Humans are always the basic group in most fantasy world, being very similar, if not identical, to our world's humans. I'm my game I want to change the idea of a human. You'll still be able to make the standard ape evolved human of our world but that's only a small group of human.
My game will have three major species: Fae, Homunculus, and Humans. The only trait that all humans share collectively is that they are flesh, but this is not the rule as some minor species also share this but have other traits that separate them.
Being that they are made of flesh, humans more often than not display characteristics of animals, and by extension, gain similar benefits. I'm personally not going to designate specific racial groups as all humans can procreate, but there are, for lack of a better term, categories that people fall into based on physical traits.
Dwarves
Dwarves are often denoted by poor eye sight, powerful noses, and shovel-like hands and claws. Commonly taking traits from badgers, gophers, moles, and shrews. Due to this subterranean advantage, they often form cities in mountains and underground alongside Homunculus.
Centaur
Adventurous Centaur are often sought for their switches in combat. Running on four hoofed legs while being able to wield a weapon makes them excellent warriors and casters. Other than their shared ungulate like legs, centaurs can vary wildly depending on their heritage.
Giants and Trolls
Giant is rarely the only term used to describe someone, and usually is the preface to their other indicator. Giant centaurs may be similar to giraffe or giant orcs are elephantine.
Goblins and Halflings
Goblins and Halflings are two sides of the same coin, often just any human that is a shorter stature than standard humans. Goblins are typically nocturnal or subterranean while Halflings live in the sun.
Minotaur and Satyrs
Similar to Centaurs, Minotaur and Satyrs have hoofed feet but only two legs. Minotaur are also typically grouped with giants as they are just larger Satyrs.
Orcs
A muscular build is common among Orcs but the true denoting feature of an Orc is their prominent tusks. Orcs share many traits of other tusked animals like boars, elephants, or walruses, but can appear as many others as well.
Triton
Triton is an extremely broad group as it refers to any humans that live the vast majority of their lives in the water. Typically you will refer to a Triton group with a secondary term. A Triton Dwarf maybe a deep sea Triton, a Triton Giant likely resemble whales, and Triton Satyrs are similar to sea horses and hippocampus.
