I don't know any entities rather than Angels, Demons, elves, faeries. But I have heard there are Many different types of entities, so I would like some people to share their names and some information about them..and maybe the experiences they had with some of them. For other people and I to learn.
Personally, I don't categorize entities so much. Elves, fairies, goblins, demons, shades, jinn are all essentially the same thing when you go back to the root of these beings, often being chthonic beings rooted in animistic practices, with stark similarities.
Angels, archons, aeons tend to be a little different as celestial beings that are essentially the beings that manage the fine mathematics and laws of the universe, bizarre alien beings made of spinning geometric shapes, animal/human parts, eyes, and fire.
I tend to rather think on beings in terms of celestial and chthonic spectrums.
If you are to ask me,there are only two types of beings:physical and metaphysical.
The second are non corporeal,being made only out of different types and amounts ofenergy, while the first are metaphysical ones that manifest themselves in a physical vessel (body).
Energy can shapeshift and thus there appear different kinds of metaphysical forms (agels,fairies,dragons,etc).
Matter can group itself into different shapes as well so there are different species of plants,animals,etc.
I hope this helps ^.^ This is solely how I see it. Two big races divided into so so many classes,subclasses,families,etc.
First, I rather class them as "spirits" or "beings". They are all basically the same things. They are energies. Some have died like the normal term for a "Spirit" a deceased loved one and some have never been human or had flesh. Some are seen as bodies and some are seen as orbs, lights, flashes, shadows. I recommend researching folklore. Especially Celtic Folklore as they have info on fae. Try looking at some poems from W.B Yeats, an Irish poet, I'm Irish myself and I love his work. He wrote alot about faeries and I believe he saw them when he was alive. Just research and learn as much as possible. Mail me if you need to!
i have a bond with a celestial being up there.. well, just cause i spelled a spell 4 years ago.. a shiny yellow light appears around my body... then i'd go to the (sky sanctuary ?). we'd make a serious deal and wwaw.. i just still cant believing what i saw
