I've worked out several of these for the Viksor:
LIST OF VIKSEN LEGENDARY CREATURES
The ætu (Diffian èstoliþ, Jaxaran sètol) is regarded as the Viksen equivalent of the vampire. There are different in several ways from European vampires, however. Viksen vampires are said to appear in the form of beautiful humans and to seduce their victims before eating them whole. In the version of the legend that is best known today, ætu’d are usually male and target virgin females.
The ætu’d are not “undead” but are said to be outcasts from humankind, punished for seeking immortality or beauty by requiring human flesh to stay alive. If they do not eat they gradually begin to transform, either into donkeys or fungus patches depending on the legend. They are usually found in forests and are associated with certain kinds of tree, particularly the ash, often being said to have a “home tree” in which they hide.
West of Diffy, the equivalent name for the creature is sædu. This term is becoming less common due to media influence from the east, although it is found in a few well-known works of fiction.
In the early Viksen religion, the Soul-Egg Hen was a mythological red chicken that laid eggs into which the soul of another creature could be placed through the application of the correct magical spell, as long as this spell was performed within a day of the egg being laid. The Hen would incubate the egg for one hundred (Venusian) years, after which it would hatch into a creature bearing the original soul. In later Damaist folklore, the soul could be placed into any hen’s egg, the time of incubation was variable (from thousands of years to a few seconds or minutes), and the creature that emerged would usually be depicted as monstrous.
The Life-Egg Hen was originally the sister of the Soul-Egg Hen. She was coloured white. Her eggs could be eaten and would bring about extended life and good fortune.
The father of the two hens was Źakhan (Jaxaran Yakakan, Diffian Yakhanath). He had one thousand wives, but laid the eggs from which his two daughters were born himself, without recoursing to females (other accounts say he gave birth like a mammal). Źakhan was the son of the sky mother Mai but chose to come down to Earth, where he had his own land called the Meadow Kingdom. He was rash and foolish and made war with men, but lost: his kingdom and his wives and children were taken from him. Źakhan was coloured black.
Ghosts may be left behind when a person dies, usually by a conscious act of will. The ghost is not the whole of a person’s spirit, and is generally restricted to a distillation of the more inhuman, malevolent, aspects of their personality.
The Golden Fish are said to turn into solid gold when captured (in life, they have golden-coloured scales). However, they must not be injured in any way when removed from the water, and should instead be allowed to asphyxiate naturally. There are two different traditions of the effects of damaging in some other way. The first says they will either turn into ghostly fish-spirits which forever haunt their killers. The second says they will bleed uncontrollably, with black blood that burns up everything it touches. This bleeding can only be stopped by throwing the fish back into the water (or by throwing water over the fish).
Great Black Bird
The Great Black Bird was the king of Mercury, the Sky Planet. With a wingspan that could cover an entire kingdom, it came to Venus, where it was defeated by the White-Faced Man. However, it laid a number of eggs, which also had to be destroyed subsequently.
Moths in some early Viksen legends are said to be the manifestation of the souls of the dead. This evolved into a tradition whereby evil sorcerers might temporarily transfer their souls into large black moths in order to leave their bodies, which further developed into the idea that moths (and butterflies) may be used by both good and evil to send messages (for example, to a loved one).
The nu (Jaxaran nol, whence Diffian nolaþ) was a fearsome elephantine monster. It was described as like an ox, the height of several men; horned, with clawed feet like those of a lion; long-tailed; with red eyes, large ears or sometimes wings, and a strange appendage on its face by which it strangled its victims like a snake and then used to suck their blood or swallow them whole.
In modern Viksen, nu means simply ‘elephant’.
The pinaba (Jaxaran penam, Diffian pinaboìþ) was a giant water-dwelling creature. It may have been inspired by real-life sightings of the giant squid, and pinaba means ‘squid’ in modern Viksen. The third-century writer Kriku, in his Bestiary, describes the pinaba as follows:
“This monstrous creature is as long as the height of three hundred men, although some two-thirds of this length is made up of its great tentacles which trail behind it and in which many ships have been caught up. The main body, green in colour, is set about with eight great red eyes, allowing it to see in all directions. The mouth has two great protruding lips surrounding a long red tongue, and inside is set about with many thousand teeth of terrible sharpness.”
Several spiders appear in Viksen mythology and folklore. One of the most well-known is Yizu (C.O.V. Elæzaþ), adopted from the mythology of Ichi. Yizu is a great spider warrior who travels the world looking for adventure. He has several magical attributes, such as the ability to change his size and even to adopt human form on occasion. The aim of Yizu’s adventure was originally to replace the leg he lost in battle; however, it is said he enjoys his great journey so much he would probably continue even if he regained the leg.
Ńavagi (‘the red one’) is described as a great bloated red spider, perhaps a foot wide, who lives on the blood of humans and livestock. She is impossible to kill, as she will always respawn from one of the vast supply of eggs kept in her fortress, where she is waited upon by smaller spiders. Ńavagi is said to have killed her own husband and eaten him. In alternative versions of the legend, there are many ńavagu’d of both sexes, though they are no less dangerous.
Giant spiders are said to roam the deserts and mountains to the north of the Viksor. They are many times the size of a man and deadly to all who come across them.
Luck spiders are associated with good fortune, and are particularly said to be able to bestow good skill with the needle upon young girls who they favour.
The wug (Jaxaran úg) is a troll-like creature described as being shaped somewhat like a man, neckless, short-limbed, covered in brown or black fur, with yellow (sometimes red) eyes and a mouth full of sharp teeth. These creatures live in tribal groups in mountainous forests and prey on human beings and other creatures.
Stories of the zey’d first appear in the thirteenth and fourteenth centuries; the name is believed to be onomatopoeic (representative of the buzzing sound of flying insects). The zey’d take the form of small black flies which exist in great swarms and emerge from food that is thrown away and left to rot. They will eat all the food left in a house in a matter of minutes. Beyond this, zey’d are not considered particularly dangerous. Yizu the spider is said to be the enemy of all zey’d.
