I've decided to give the whole Alpha, Beta and Omega theme a go for Rivamika and well, I'm not promising over it being any good. It's going to be zombie apocalypse au as well since I know a lot of you rather enjoyed my past zombie themed books. 

Alpha:  Alphas are the top dogs within the human race. They'll be the most skilled and how the most power. They'll be respected and are mostly working in high class jobs or as a person boss. They'll be seen as the best of the best and have great pride for being an Alpha. An Alpha can control if they leak their pheromones or not, most do without a care that it can force an Omega into an early heat.

Omega:  Omegas are the most looked down, they're seen as someone who only popups is to have an Alpha child. They seen as sex slaves or toys for an alpha to have or even for Betas to pay for to have a good time. They don't have many rights or respect in the eyes of the world. They go into uncontrolled heats once a month. Omegas only leak their pheromones during their heat making Alphas lose themselves to instincts and attack an Omega sexually.

Beta:  Betas are the background characters mostly. They serve under Alphas and are expected to never be better then an Alpha but always be better then an Omega. They keep the world running and just live the basic lives. Its rather rare for a Beta to get a high class job or become a boss but it can happen rarely.

So, Notes over my version of the whole Alphas, Betas and Omegas world. Along with how it's all going to work in a zombie world.

Fact 1 - Female and Male Omega have a week long heat once a month. It makes them into a horny and lustful mess since their bodies are ready for an Alpha to take hold of them and reproduce. Female Omegas will only have a monthly heat and not have a normal period.

Fact 2 - Omegas can take a heat suppressants pills or an heat suppressants injection to control their heat during the one. It keeps the Omega pheromones hidden away and keep the Omega in full control over their body letting them live a normal life even when in heat. Some pills will be more harmful for an omega body and some pills or injections with have side effects on the body but nothing deadly.

Fact 3 - Only an Alpha and Omega can form a fated pair bond. No Beta can give a paired mark with an Omega or Alpha.

Fact 4 - Beta's can impregnate an Omega or Alpha. A male Beta and female Alpha can still have a child together and a Female Beta with a Male Alpha can still have a child together. A male beta and a male Omega can still have a child together but only when the male omega is in heat. A female beta and male omega can have a child, only with the female beta getting pregant. A female Beta and Female Omega can NOT have a child together.

Fact 5 - An Alpha can have more then one fated bonds with Omegas while an Omega can only have one bond. In my version of the story - a bond can be broken without having the Omega have to die weakly afterwards. So, a fated bond can be broken by the Alpha at any time or by the Alpha death. Omegas don't hold the power to break the bond themselves unless they meet their true fated pair and then the bond with magically break for the Omega to belong to their rightful Alpha.

Fact 6 - When an Alpha and Omega have became a fated pair together, only the Alpha will be able to smells its Omega pheromones. An Omega also will not have anymore heats, well they still have heats but not as bad before having a fated bond with an Alpha. It be more subtle and easy for them to live with without ever having to take heat suppressants pills again unless its the first heat after having a child since that be more burstful then any heat before.

Fact 7 - This is a zombie apocalypse and once a person becomes a zombie they lose their Alpha, Beta and Omega bloodline link. No Omega zombie or Alpha Zombie will have their second gender instincts within them after turning. A zombie won't have any second gender pheromones or heats.

Fact 8 - The zombies can only die by having their brains damaged .. none of that heart bullshit.

Fact 9 - The Zombies will be attracted to sound, there smell won't be too powerful since they would be rotten corpse themselves, they'll only smell living flesh if it was standing right before them. This also means the humans can bath or shower with soap without having to rub themselves in zombie blood after.

Fact 10 - The Zombies will not be super fast, even I'm not that mean. They'll be slow but can run a little .. more like jogging after their prey once locking onto them in a sense. They won't be too fast but not as slow as a nanny run.

Fact 11 - An Omega heat suppressants pills or heat suppressants injections won't have a due date, they can work no matter how many years pass.

Fact 12 - I'll most likely be guessing as I go along, so there may be mistakes or loop holes used within this story.

Fact 13 - Oh right, one in a hundred Beta's can chance their second gender, either becoming an Omega or Alpha. They can't chose and would find out by their sixteenth birthday when they take another second gender test to see if their second gender changed or not. One of out a thousand Omega or Alpha can also change their second gender without control, either becoming a beta or Omega or Alpha .. they find out by their sixteen birthday as well when taking another test.

Fact 14 - Time still roughly works since the space satellites are still up and working. Not really needing humans to keep them running somehow and well most clocks were linked up to them making them keep to the time and dates. It doesn't have to be a smart watch, it can be any watch since they've all been made with something .. Magical?
