MAGIC. MYTHOS. WORLDBUILDING
The Otherwise are all of the supernatural/mythological/folklore/fairytale beings who exist side-by-side with us, as do their worlds/dimensions, which are like mirror worlds of our own. The closer the world, the more it resembles ours, and the further away, the more it does not.
Think of it like layers of an onion, with the ‘core’ being ONE WORLD (what we call 'heaven' or 'nirvana' -- but you didn't hear it from me), and moving out from there. every layer is another world. Some worlds are easy to get to through gates/portals/etc, and some are almost impossible to reach. The nearer to our own, the easier, usually. Of course you’d need to have the skill to get there, or know how to use a portal. And for that you have to know where they are. and only a relative handful of beings do.
There are a good few portals in Ireland (and some in other places around the world) but they are very few and far between and they are always guarded, either by magic or by guards or both.
Portals are world-specific. You can take a portal to Fairy/Arcadia but that same portal won’t get you to Hell. Sometimes the best way to get to a farther-away world is to go through another one that’s a bit closer. Sometimes that is the only way into another world.
Time moves differently in the different worlds as well. So journeying between is hazardous to say the least. Every world has its own rules, which travelers really should learn before they go. So that they don’t break them. Also so they don’t get lost. Or stuck. Or ‘un-alived’. None of these supernatural beings or worlds are ‘known’ or ‘out’ to the general human/mortal world. Although, as always, there are stories and myths. And there are a couple of secret human societies that know.
the list of species are as follows:
VAMPIRES are human/demon hybrids created by a demonic virus which was itself created by a curse a very, very long time ago.
Vampires must be made by another vampire and their creation is incredibly painful and doesn’t always work. They don’t all know of their origins, but there are a lot of theories.
Vampires live in our world, although there aren’t very many of them left. Vampires feed on human blood and only human blood. They cannot survive on the blood of animals or anything else (although rumour has it they could drink human-hybrid beings or angelic beings).
Vampires are immortal. They can be killed, but only by sunlight or beheading. They are super fast, super strong and super flexible, with a skeletal structure akin to a cat’s (flexible spines/connective tissue, etc), so they can fit into extremely small spaces, and absorb falls/blows etc. They also heal from most wounds very quickly.
