The inspiration for it came from the internet like many other ideas that came before it. Humanity, a bipedal race of apes that evolved to be the sole sentient race on planet earth, both what if Jeff changed it. Mythological and internet driven races would dominate the world while human's would be the fictional creatures and only exist is fiction or myth.
Jeff began to create the races he imagined a world he wanted to be dominated by. His first idea would be the more common races, the ones that make up most of the population. Humans would no longer exist and magic would be in the new world however each race would be limited to what kind of magic they could use.
The first race on the list are merfolk, an aquatic race that live in all the worlds oceans. Their upper body is that off a human but below their waist is of a tail of some aquatic creature. It can be fish, sharks, whales; even sometimes octupi or eels. This race specialises in water magic.
The next race are centaurs. Like merfolk their upper body is that of a human but their lower body is that of a horse of some breed. The human section of the Centaur is different to merfolk as men are much more muscular then merman while female centaurs have gigantic breasts as they can easily hold a lot of weight due to their strong lower bodies. Centaurs are also gifted to be able to mate with regular horses, but the offspring of this connection aren't able to bear offspring themselves. This race specialises in earth magic.
The third race are the elves. Woodland human-esque creatures that are very similar to humans with the exception of their more pointy ears and endowed bodies. This race is more in tune with nature then many other creatures. They are often nudists and any clothing they do wear is velvet smooth and often semi transparent. They are the one of two races (the other being the dragon kin)to lack shame when it comes to exposing themselves to anybody. Elves possess the longest longevity then any other race. This race specialises in nature and light magic.
The next race are dwarves. Stumpy and short human-like creatures that are polar opposites to elves. They are the most technologically advanced race on the planet and are the second most common race on the planet (behind merfolk in population size). This race even created golems and Automatons to be used in their armies as intelligent weapons bent on enslaving all races. Due to their exploitation of the land, elves despise dwarves and vice versa. Dwarves also specialise in fire and earth magic.
Fairies are similar to elves in appearance but possess traits off moths and butterflies which is represented in their insect like wings on their backs. They are similar in appearance and personality to elves but they are much more smaller then elves. They make their homes in forests but don't mind using technology and clothing is worn universally. This race is mostly female but 5% of fairies are male and often male fairies end up having harems as a result. This race can use almost any magic besides dark magic depending on their heritage.
Dragon kin are a huge reptilian, humanoid race that are the rarest race on the entire planet. This race have a humanoid structure with female dragon even possessing breasts. They possess long reptilian tails and wings (although some dragon kin are incapable of flight depending while others can fly). They live in caves and mountains and are capable of controlling certain powers depending on their lineage and scale colour.
Red > fire
Yellow > lightning
Blue > water
White > Ice
Green > wind
Brown > earth
Black > darkness
Gold > all elements
Gold scaled dragon kin are believed to reside very close to the earth's core, some even said to live inside the mantle.
Another reptilian creature is the lamia. They have the upper body of a human like merfolk but unlike merfolk, they don't possess arm. They have the other human feature of merfolk but they lack arms and their elbows do not extend outwards like regular merfolk. Their lower body is that of a snake of some variety which can either be a few feet to over 90 feet in length depending on the snake or age if the lamia. This race specialise in dark magic, mostly using poison and stealth parts of dark magic.
Other races include in the new world include:
Arachne- similar to centaurs except they possess multiple eyes and have the lower body of spiders instead of horses. They use dark magic in the same vein as lamia.
Angels- similar to fairies except they are larger and have white feather wings instead of insect wings. They are capable of using a special form of magic that is gaia, aka light magic
Taurus: humanoid race with very well endowed bodies and features of a cow. Women of these species are known to have the largest breasts of all races, even rivaling centaurs but smaller then femal dragon king's chests. Female Taurus also have the distinct feature of 4 breasts due to their similarities with cows while make Taurus have very hefty penises and testicles for a similar reason. This is the dumbest race of any race on the planet and lack even the brain capacity to communicate in anything but moos. They are incapable of magic but their milk can be used to make an elixir that converts others into Taurus.
Nekomata: human like race although their only unique features are the cat tail and ear, with their hands being cat pawns. They specialise in stealth, but not in any other magic.
Doggos: very similar to nekomata except its features are that of dogs. These two races also despise each other and entries wars have been started between members of these races. They can use any magic to a simple level of expertise.
And Jeff left the Chronivac to fill in other races as he wanted to atleast be surprised by what the world will be. He also decided to include the fact that he would be the only one aware of what the world would be like so he could truly experience it without issue.
Pressing the Chronivac's input button, he watched as the changes progressed.
(Author's note: I'd love to see what other people could come up with in terms of what races would exist.)
