*See Magic & Abilities for specifics on the powers of all of the species.
Humans are the most common creatures in the realm. They are nothing special particularly, but assumed to be the most typical of all the species.
Seers in general are rare, since they cannot be bred. Most of the time, there will not be a seer related to another, since they are born at random.
Since the future is something many want access to, most seers charge people to tell them about their visions.
Seers aren't much different from humans. They are usually born in human families, and produce human children, despite whether or not their spouse is a seer too. The only difference is they see the future.
Demons are the realm rulers, and not usually pleasant people. In their community, since they are an upper class species, acting out against other demons, disobeying your superiors' rules, or questioning them is highly looked down upon. Not all demons are plagued with cruelty, but many are.
They are different from humans in which they are stronger, faster, heal more quickly, have longer life spans, age more slowly, etc. The males also have dominant genes, so they may reproduce with human females and their children will be full demons. However, if the male is human and the female is demon, they will have a half-demon child, which is considered undesirable.
Female demons also have a more difficult time getting pregnant than female humans.Â
Half-demons are created through the reproduction of male humans and female demons. It's generally looked down upon, and their magic ability is even lower than a demon's. Half-demons are also forbidden from taking the throne.
As far as anyone knows, angels are extinct. However, if the veil is taken down, those with active angel blood will become full-fledged angels.
All the remaining angels bred with humans, and therefore, some human families carry the gene. However, this does not guarantee they will be angels. For most of them, the genes will remain dormant, even if the veil comes down.
