Lisping

Lisping. He's a demon, so it's impossible to determine his age.
In Yav he has no physical form, because he is actually a demon, so he occupies the bodies of other people, but unlike all the other various beings in Yav, he tries not to harm the bodies.
In Lada it looks like this:
A tall, thin guy, about 20-25 years old; copper-red hair cascading down to the middle of his neck; amber eyes; small black horns, half hidden in his hair.
As his name suggests, he lisps, a strong lisp. He's been to speech therapists and tried everything, but he can't seem to get it to stop.
Cinnamon Bun's character is kind, sweet, affectionate, caring, friendly, and loves to cook.

Horned Raven. He's Nora's constant companion and best friend, always there for her, and is also jealous of men who show any interest in Nora. He's not as jealous of women, but he's incredibly jealous of potential suitors (likely a lot).

It looks like a large raven, the size of an eagle, with almost goat-like horns, slightly curved backwards.

He, like a real raven, at the level of the structure of the speech apparatus stretches the letter "r" in all words where it is, and it turns out not "r", but "r-r...", or "...r-r-r...", and it does not matter whether this "r" is at the beginning of the word, in the middle or at the end - this "r" will still be stretched.

Formerly Svyat Burov, but due to some bad relatives, he died in a car accident. The Cat gave him a temporary form (a tall, dark figure in a hood, long robe, and horns on his head) and left him to find his own form. He followed Nora for a while, but then she turned him into Raven, and at first, they couldn't even stand being on opposite sides of the apartment—they both became very ill. But later they became friends, and now they're inseparable.

Nora. Nora has light, faded brown eyes; wavy, shoulder-length hair; tall (172 cm); slim; beautiful. 20 years old.

Her eternal companion is a large (eagle-sized), talking, horned raven.

Nora has a rather gentle and kind nature, but when necessary, she can be stern and collected, making the right decisions. She's very forgiving of people and friends.

Yak. He served in the Guard for 500 years, but broke his contract, but since the Guard won't let him go, he's still alive.

His appearance is appealing. Bald, but with a short, dark red beard; blue eyes; and a strong build. His physical age is approximately 50, but his actual age is 550, as the way service in the Guardians works is that from the moment you sign a contract with the Guardians, your physical age stops.

Yak has a fairly calm character, with a sense of humor, but at the same time he is a wise leader.

Brut. He was Yak's deputy, and later became Skat Ivanovich's deputy.

He has brown slanted eyes (the outer corner of the eyes is slightly higher than the inner one); dark red +/- short hair; no beard or mustache; slender (but Raven calls him a weakling, a punching bag (because Brut managed to beat Skat Ivanovich a couple of times when they sorted out their relationship, when Brut tried to blame Skat Ivanovich for his actions)); slightly taller than Nora (175 cm). Physically 23 years old, actually 123, due to the fact that he has already served in the Guard for 100 years.

Incidentally, Brut is a nickname Yak gave him for his personality. Brut is actually a dry sparkling champagne. So when Yak asks Brut, "How's the champagne situation at the office?" it's Yak's playful way of asking Brut, "How are things?"

Brut has a dry, stern demeanor and a rather harsh personality, but he treats Lisp and Gleb almost condescendingly, more like younger brothers. Due to a negative experience on an important matter with the centenarian Shura (whom Brut calls Shura-the-fool), he dislikes centenarians (but this doesn't extend to Nora. Even when Brut tries to feel the same hostility toward her as he does toward the other centenarians, it doesn't work).

Real name unknown.

Skat Ivanovich. I don't know how old this fucking imbecile is.
Now the head of the Guard. But later it turns out that all those several murders and many other bad things were done by him or his community.
A very tall man (when he enters a room, the top of his head hits the ceiling); blue eyes; a beard; short hair with graying; strong, powerful. About 90 years old, maybe even much older (well, he has a great-grandson, so to speak), but still wow, and can give younger people a run for their money.
His character... well, he's a complete scumbag. First, he killed his own brother, then most of his Burov clan (yes, Skat Ivanovich isn't his real name, it's Vyacheslav Burov), and then he cut the wires in the car of his great-grandson, Svyat Burov (now Horned Raven, or simply Raven), and he crashed his car.

Gleb. 20 years old.
He is a Guardian trainee, which means he has not yet signed a contract with the Guardian, which means his physical age has not yet stopped.
He has brown eyes; short straight hair, dark hair; tall; one could say thin. The ability to sense people, to see right through them.
His character is very similar to Lisp's - kind, sympathetic, sweet, affectionate, sometimes reckless.

All sorts of different things are evil spirits, of all sorts of appearances, various types of creatures.

Classifications:

SMALL:
A kikimora is a small, fox- or rat-like creature that wraps itself in various rags. All four limbs resemble chickens, and kikimoras walk on their hind legs. They eat absolutely anything, and are especially fond of chewing on someone's pants or sneakers.
Brownies rarely show themselves, but when they do, it's only for a moment, and they look like a large, shaggy hat, possibly with a beard. If a brownie dies, a single, tattered slipper is left behind somewhere.
Biryuk is a petty devil. If you curse, it might appear to you. It takes on different forms, each person's own. Biryuk feeds on fear, so you shouldn't look it in the eyes if your fear has a form. But if your fear has no physical form, it will appear in a form resembling a large, hairless cat, with large black eyes, large ears, small horns behind the ears, and a long tail.
If, out of frustration, fear, or something else, you say “Damn it!” or “Damn you!”, then the exchange will immediately appear next to you and respond with “Aha?”, “I’m here,” or “So why do I need him/her?”

AVERAGE:
Auka—no one knows what they look like. They most often live in forests, calling to lost travelers with the voices of their loved ones.
Demons are more mischievous, vicious, aggressive, and energetic. They can appear in different ways.

THE ONLY ONE:
The oyster is a pestilential bird, creating and transmitting diseases. But by nature, it's quite docile. Its crooked beak, thick body, and small wings make it agile when needed, yet its speed at the right moment would make even a peregrine falcon envious.
Hunting is her head. Enormous birds, like crows. There are a lot of them.
The likho is an exceptionally vile, harmful, and dangerous creature. It and the oyster are essentially one and the same, but the likho is completely uncooperative and very evil. It appears as a thin, tall creature with gray skin and a long blue tongue that doesn't fit in its mouth. It becomes more powerful when it devours human souls.

The Great Tree is what sustains the Harmonious World. It is an oak tree whose crown reaches into the clouds, and its roots extend across the Field.
The "root part" of the Oak is not subject to temporary changes in trends, and has preserved traditions since the creation of the Ladny World, that is, somewhere around the year 1000, for the Ladny World is 1000 years old.
The "crown" of Oak changes in step with the changes in Yav, and completely mirrors it, so that in both Lada and Yav, being in the same city, you can easily walk along familiar routes.
The Field is a vast field of wheat, stretching far, far beyond the horizon. In the center of this field stands the Great Oak.
The Field itself is a place where the souls of the stubborn end up, and there the souls decide whether to go to a new circle or stay in the Field.
Each grain on the ears is a soul that decided to stay in the Field.

Yav (the Manifest World) is our ordinary world, without any different things, or rather, in Yav they do not have a physical form.

Lad (the Ladnyy Mir) is, one might say, a branch of Yav that emerged much later. It has many more rules regarding communication with all sorts of beings, handling magic, and so on.
The fret has a root part and a crown part.
