While this story will have classes and stats, it will not be like a game's class system. The classes are just terms used to describe a character's Talent. The stats are just a guideline that I'll use to keep track of the strength and growth.
This story contains many different races alongside humans. Some will be peaceful, some will be warlike or just naturally destructive and others will contain a mix of both. The races are normally named by the person that discovers their existence when they are put into the human database. The other races call themselves something else in their language, but refer to themselves by their human titles when conversing with humans in their(human's) language. Here's a list:
-Human race: Humans are a versatile and diverse race that rapidly grows and expand, but due to the own greed and civil strife, they tend to take more steps back than forward which has caused their expansion to come to a standstill at only inhabiting about 20-22% of the Milky Way Galaxy.
-Titan race: The Titans are an alien race of giants. Their statures give them great strength, but their main focus is energy based and they are capable of bending the elements to their will. Their are only capable of using Fire, Water, Wind, Earth, Lightning, and Metal elements, but, while rare, there is a possibility that they can be born with a talent in an advanced element like Ice, Lava, or Light. There are incapable of using Space or Time variants of the elements until they achieve a certain level of strength like the rest.
-Draconids: This is a alien race that resembles they dragons of legend. They can shift from a full dragon form to a humanoid form. This race is powerful and arrogant and are known to covet what others possess. This causes a lot of strife between them and other races, but there are some who uphold a strict code of honor and diplomacy. While strong, Draconids take a long time to mature and grow to their full potential, but they tend to die young as their lustful and greedy nature alongside their arrogant outlook causes them to pick fights with others without making sure that they can win or escape.
-Elven race: An alien race that resembles the creatures of fantasies. This race is peaceful by nature and prefer to stay on their own planets full of life and vegetation. They are allied with the Dryads and have a peace accord with the humans. While peaceful by nature, they are by no means weak. Then are naturally attuned to the elements and have great great martial prowess. All who have tried to pillage their lands or kidnap and/or enslave their people have paid dearly.
-Dryad race: An alien race of intelligent plant life. Some appear more humanoid than others as they are as diverse as the plants they resemble. They are peaceful and are gifted healers and producers. Their prefer to live on planets with thick vegetation and normally occupy they same planet as their allies, the Elven race. They become aggressive towards anyone that threatens the forests they inhabit and are highly dangerous in any area with many plant life.
-Harcosok race: A powerful alien race on par with the Titans, Draconids, and Hecatoncheires. While there stature is not as large, they make up for it with their might. This race is born with immense strength and have to wear an armor that acts more like a restraint and suppresses their power, so that they can gain control over it and become stronger. While their do possess an affinity for energy growth and manipulation, they mainly use it to enhance their own physical qualities to a frightening degree and due to their smaller size, this immense strength in focused into a smaller area than with the giant sized races and their speed is a whole lot faster. This combination makes them feared throughout the galaxy. This race acts as warlords within the galaxy and is an enemy to everyone they have not already killed or conquered.
-Iszap race: An alien race of living metal. They are born from the very planet itself and have the appearance of a blob of slime with no defined shape at first. They feed on metal and ores in the planet, but can sustain themselves with other things too, though other things besides metal won't facilitate their growth. The more metal they eat, the stronger and bigger they get. Once they achieve a certain level of size and strength, they are able to compress their bodies into a humanoid shape. Some even take the form of land based creatures, but they can shapeshift their form at anytime. Due to their growth methods, their bodies are very durable and hard to damage. They are living nightmares to machines and cyborgs, but, luckily, after they are able the change their forms. they gain a sense of awareness and basic intelligence, so as long as someone communicates with them, they won't attack or eat any machinery unless provoked.
-Formorian race: A race of giants with grotesque forms. These malformed creatures possess great strength and strong bodies, but are incredibly dim. The have no affinity with energy manipulation nor are they attuned with any element, but they can live underwater. They mostly choose to live in murky or dark waters, so that they can high their giant grotesque forms. They see everyone as a target an will eat anything whether it's sentient or not. It's unknown how such a race has spawned on multiple planets, but they are a threat to everyone that isn't of their own race and so, they are hunted down whenever another race tries to colonize a planet that they appear on.
-Yaoguai race: A diverse race of aliens that include multiple forms and bloodlines. Each is like their own race, but they always live together on the same planet an while humans would refer to them by their separate races titles when talking about or to a specific one, they'll refer to the whole as Yaoguai due to their similarities to the myths and so as to not have to list every single one during a conversation about them. Due to their diversity, they have a wide array of abilities and talents. They tend to take a stance of keeping their bloodlines pure, but every now and then a hybrid will appear. They call these hybrids Mongrels, cause most of the time, the mixing of races will cause the person to not be able to use either races abilities and even their physical abilities will be weaker. Their are rare cases of it being the opposite though. Their are sometimes cases of a Mongrel being born stronger than either race. It's unknown as to the cause of the differing cases.
-Skordyr race: An alien race of insectoids that live to expand their colonies and conquer and assimilate other races. The strengths and talents are determined by the form they are born with and their purpose within the hive. The progress and evolve with the growth of the hive. As the hive grows, the rest can evolve and later the stages of evolution are more dangerous, so other races try to destroy any discovered hive while it it small and weak. The hives are ruled by a hive mind cluster. The cluster acts as the king of the hive and determines what is born from the hive. After the clusters, there are the queens. The control the lesser ranks and give birth to more eggs that hatch into an assigned role or form. Each planet this race inhabits could contain multiple hives each with their own cluster. The hives also gives birth to a slime-like fungus that encroaches on the planet and blankets the surface. This fungus acts like a food source for them. When a hive grows to a certain size, it produces another cluster. This cluster is given one queen and hive seed by the parent cluster with a couple of drones and fighters. They are then sent away to start another hive in order to expand the colony. If there is not enough room on the planet, then they'll be sent off world to start colonizing another planet and to assimilate the species that lives there. All hive are connected to the ones they are born from. This creates a sort of network between all the hives that exists, going as far back as the oldest and strongest hive in existence. They only way to sever this network is by destroying a parent hive. The hives born from it will no longer have access to the rest of the hives and their growth will be slowed down.
-Demon race: An alien race of strong humanoid beings. They use a different form of energy called Youki. They have outstanding physical might and almost instantaneous healing. They can disguise themselves as any other race by possessing someone of that race in order to infiltrate them. Once the possess someone, they obtain all their memories and are able to mimic their mannerisms completely and are able to answer any question you ask them just as they would. The ones the possess are alive for a short while, but once all their memories are assimilated with the demon so too is their body. At that point, the possessed dies and ceases to exist and their physical body merges with the demon's. While they are hidden within a civilization, they'll maintain their host's outward appearance and actions during the day, but at night they'll hunt down and consume others of their host's race. They'll never attack their host's family so that they can act as a smokescreen for them, unless they think that their is any suspicion on them, then they'll take out a few to make themselves seem like one of the victims. They get stronger as they feed and are known to have wiped out entire cities when they are strong enough or if enough of them are present in the same city. Humans have experimented with the genes of defeated demons and merged them with willing human test subjects. The humans gain the ability to use the same energy as the demons and are able to sense whenever a demon is near. These people are called Demon Slayers. Though, while demon slayers are strong enough to kill demons, they use Youki in every fight. This has caused a new issue to arise. Youki is naturally corruptive and as they use it, they are constantly in a battle of will to not give in to its beckoning call. Those who do become monsters far worse than the demons and develop a more voracious appetite for their own race. The monsters they become are known as Asura. Asura form and abilities are determined by the strength and talents of the Demon Slayer the it was before. They only way to make sure a demon or Asura is dead is by decapitation or by destroying its brain.
-Hecatoncheires: Another alien race of giants. They have no talent for magic, but make up for it with their strength and martial prowess. These giants are born with four arms and can grow more as they get stronger. The number of arms they possess ranges from 4 to 1,000. They are way stronger than Titans when it comes to the strength and durability of their bodies and can out perform them with their martial talent. They have a ridiculous healing rate and are able to turn their energy into a massive well of strength. This ability is normally only used when they go into a berserk state due to extreme anger, as it'll leave them temporarily weak afterwards. They prefer to keep the energy full and use it to hasten their healing ability so that they can fight for an extended period of time.
-The Infection: An alien race made up of a living sentient virus. The infection is a monstrous blight on all living things. Those that are infected become mutated masses of malice, hellbent on spreading the infection to others. The infection has different effects on people as it is an amalgam of different strains that seemed to fuse together and it targets every living thing, even the plants. Any world that has an outbreak is normally abandoned and burned, unless the infection is caught and destroyed in its earlier stages.
