Lunar is a different realm, its not a part of Earth. 

Lunar is a place where every supernatural creatures are found. Like Ware-wolf, Vampires and witches.

They live in peace between them, the three of them has there own leader who is there to maintain peace and to solve problems between them. 

The Whole of Lunar is Ruled by a King, a royal Blood. All decisions for the whole supernaturals are made by the King. For the King the whole leaders of different supernaturals work. The the leaders are selected by the king and the people in his ministry, where people from different supernaturals are selected 

In every creature there is Alpha, Beta and Omega

Alpha are strong, possessive , and always dominant

Beta come after the Alpha they are stronger than Omegas but not upto Alphas they can a top or a bottom.

Omega are always submissive and always a bottom sometimes when both omega mates it can be different.

True Blooded Alpha, they are rare only a royal blood will be a true blood no one can defeat them they are possessive than Alphas and very dominant

In Lunar there is only One True Blood Alpha and that is the King.

Every Supernaturals have mates, it can be of any creature. If there mate died or rejected then they can mate with anyone except the True blood, True blood cant mate with anyone because no one can control him rather than his mate.

Having human mates is very special in Lunar and very rare too. 

Human mates have more alluring smell than anything, its said that they are good in bed too so many creatures try to abduct or try there taste of them.

therefore humans protected in a shelter till they find mates

Special males from humans are rarest of rare, getting them as mate is considered blessing there is only 1 or 2 in the Lunar 

Humans are not born in Lunar, even when human mate with other creature then their child will be only a supernatural

Humans comes to Lunar only once in a year when portal to realm opens and humans having mate in the lunar will be send through a portal 

Males cant get pregnant in lunar but onlu special humans can.

The supernaturals lives more than humans in this realm after getting mated humans will also live according to their mates age.
