Mud-blood:

An omega or a vampire born from a half-blood alpha and omega/beta

Hybrid:

Is a vampire born from a pure-blood alpha and an omega. 

How do you know which you are?

At birth, the doctors will announce the gender(male or female) then do a test to find out you second gender (Omega, Alpha or beta)

What are the three roles?

Alpha: Alphas are the top of the top. They are usually pure-bloods and are never look down on. They are the aggressive ones and tend to get angry easier. They are normally the ones that finish the fight whether or not they start it. They become very protective of their young and mate. They never die and can't be killed. Their powers are the strongest and they can be feed off of but prefer not to. They are the larger and stronger ones, the dominant ones in bed. They are the males or females pumped full of testosterone. The females work differently from the males though, they have a smaller chance then most at getting pregnant at all, but they can impregnate. Once she gets aroused the area where the female's clitoris is a retractable penis is there instead. Since she has a very small chance of conceiving a child, her womb would be smaller. The female Alphas breasts would grow so she could help feed the newborn child. (Males Alphas breast don't grow) All Alphas have larger penises and are the ones to fight over an Omega. They can mark their mates and it will be permanent. A pureblood is an alpha born is the strongest kind of alpha and can make anyone they wish to bow down.

Betas: Betas are usually the half-bloods but on a rare occasion can be born from two Betas. Betas are just chill, they don't really start fights unless their young or their mate is threatened. Their powers tend to be on the weaker side. They too will never die but they can be killed, however it's nearly impossible. If a pure-blood decided it they will be fed off of. Sometimes even a female Alpha and a female Beta would be able to reproduce. They can also mark their mates though it will fade over time and have to be redone

Omegas: Omegas are the lowest rank and are the ones who are fed of off. They can live forever but are easy to kill if they don't have a mate. They are looked down on by everyone. They can be born of two betas, two omegas or a beta and omega. They are called mud-blood regardless of who they are born to. They are seen as weak as they don't usually have powers, they tend to be very submissive to those who feed off of them or the vampier voice. They are the ones seen as the primal food source. They are also the only ones where both genders that can have children. Omegas are the softer and more gentle of these roles. They are the nurturing parents who raise their children and they are the only ones in here who can get pregnant the easiest besides Beta females. The female Omegas use their systems as normal, getting pregnant that way and then nurturing the child like they should. But for the males, it is very different. All Omegas go through heats. Omegas are the smaller ones with less muscle and smaller penises if they are male. Their mark will not stay on their mate unless they are fated mates

What is knotting?

Knotting is where an Alpha's penis enlarges at the base to lock inside the Omega, giving them a better chance at breeding and producing offspring. Also symbolizing the completion of the mark. Once the knot is inside of the mate it can't be removed until fully gone down or it can cause pain to both sides.

what is a marking?

A mark is a claim that that person is taken and no longer available. Everyone can be marked but alphas don't tend to allow themselves to be marked. Betas allow themself to be marked only if they are truly in love with the person. Omegas tend to only get marks for food reasons as alphas don't tend to like to shear their food. A mark is where you bite into the scent gland, an alpha and fated mates can mark their mate at any time however betas and Omegas (if not fated) have to do it during the knotting process. The Omega has to be fated to the alpha or Beta for it to be a permanent mark or it will go after a day. A Betas mark has to be redone every few years as it will begin to fade. Marking is a way to show what is theirs and is to ward off any other alphas/omegas

what is a scent gland?

Scent glands are found in the junction between the shoulder and neck. Everyone's scent is completely different, Alphas have a stronger more musky scent but not necessary, Betas have a range depending on the person and Omega's have sweet scents. Scents are also a way to express strong emotions. A fun fact is male omega scent changes slightly when pregnant giving it more of a milky scent which grows milker as the pregnancy progresses. Mates show affection by rubbing their scent glands together. It is seen as a sexual act for a mate to lick their mate's scent gland which is more for an alpha thing to do.

What is a heat?

During their heat omegas are most fertile. During heat the reproductive parts (Asshole or vagina hole) grow slightly bigger to help ease any pain. They also produce slick which is a natural lube made by only the males, it tastes sweet to their mates. If they have an Alpha mate, they will never leave their side unless they need to get their Omega food or water. They mainly have sex and then rest. They keep a watchful eye over their Omega, listening to them and caring for them. But in bed, they still are the dominant ones. If an Omega has no mate, that could be dangerous to even leave the house. So if they don't have a mate they lock themself away and use toys to get through it. During these heats, the hormones in an Omega go all crazy. A strong scent is released during the heats, causing the Alphas to smell it and chase after the Omega. If there is already an Alpha with that Omega, they will fight the other Alphas off. There are pills to stop the hornyness and heat for a while and patches which go over the scent gland to duel the scent. A heat happens once a month

What is a rut?

A rut is an Alpha version of a heat however they are more aggressive and dominant during this it can be brought on by an omegas heat. While in a rut an alpha is highly aroused and will seek out an unclaimed omega to mate with, if they have a fated mate they will go after them. A rut length and when it happens also depends on their mate's cycle, it normally ends around the same time as their mate's heat (if they have an omega)

What is mating?

It is basically where you and your mate make love (have sex). The mark is made sure the first mating session. A mates body can withstand their mate in every way so once one is marked they can withstand a rut/heat

What are fated mates?

fated mates are extremely rare and hardly ever happen. Begin a fated mate means you are destined no matter what and are drawn to each other instantly without knowing as it is your second genders connecting. Once you have marked and mated (Have sex) with your fated mate your powers will become more strong and intensified.

What is a nest?

A nest is usually a place where an Omega can be comfortable, whether if he is in heat or just having a bad day. It can be a closet or a couch, a small room or a bed. It will usually be filled with soft things, the most smelling like his/her mate if they have one. It usually makes them feel comfortable at all times, even if they feel they are about to murder someone. With Omegas being the small fragile creatures they are, it can help them rest. As they get closer to their delivery date, they will most likely spend more and more time in their nest with their Alpha.

how does pregnancy work?

Pregnancy is about the same as in the real world. for Betas at least. For the Omegas, everything sort of changes and flips their world around especially one who has never had a child before. The male Omegas breasts becoming slightly bigger (not enough to notice but there is a slight difference) The Omegas will most likely be happy about having a child. The Alpha will become more and more protective of not just their Omega but also the small child growing inside of the Omega. Around the second month of pregnancy (8 weeks) the scents start to give off a milker smell.
