Balaur

A balaur is a creature in Romanian folklore, similar to a European dragon. A balaur is quite large, has fins, feet, and is polycephalous (it usually has three, sometimes seven, or even twelve serpent heads). As a traditional character which is found in most Romanian fairy tales, it represents Evil and must be defeated by Fat-Frumos in order to release the princess (see also Zmey). It is also believed, in Wallachia that the saliva of a bălaur can form precious stones.

The term Balaur (Macedo-Romanian bul'ar) is of unknown etymology. It has been linked with Albanian boljë ("snake") buljar ("water snake"), all terms possibly stemming from the same Thracian root, *bell- or *ber- "beast, monster", the traces of which can also be found in the name of the Greek mythological heroBellerophon ("the beast killer"). The Transylvanian Saxon balaur "dragon", and balaura, an insult term in Serbia, are borrowed from Romanian. The Serbo-Croatian blavor/blaor/blavur ("European legless lizard") is cognate with balaur, and it is regarded as one of few pre-Slavic Balkan relict words in Serbo-Croatian.

Boggart

Boggart is one of numerous related terms used in English folklore for either a household spirit or a malevolent genius loci inhabiting fields, marshes or other topographical features. Other names of this group include bug, bugbear, bogey, bogeyman, bogle, etc., presumably all derived from (or related to) Old English puca and Welsh bwg with the same meaning (itself a probable loan from the English bug).

The household form causes mischief and things to disappear, milk to sour, and dogs to go lame. The boggarts inhabiting marshes or holes in the ground are often attributed more serious evil doing, such as the abduction of children.

Banshee

The banshee (/ˈbænʃiː/ ban-shee), from Irish: bean sí [bʲæn ˈʃiː] ("woman of the sídhe" or "woman of the fairy mounds") is a female spirit in Irish mythology, usually seen as an omen of death and a messenger from the Otherworld.

In legend, a banshee is a fairy woman who begins to wail if someone is about to die. In Scottish Gaelic mythology, she is known as the bean sìth or bean-nighe and is seen washing the bloodstained clothes or armour of those who are about to die. Alleged sightings of banshees have been reported as recently as 1948. Similar beings are also found in Welsh, Norse and American folklore.

Basilisk

In European bestiaries and legends, a basilisk (/ˈbæzɪlɪsk/, from the Greek βασιλίσκος basilískos, "little king;" Latin Regulus) is a legendaryreptile reputed to be king of serpents and said to have the power to cause death with a single glance. According to the Naturalis Historia of Pliny the Elder, the basilisk of Cyrene is a small snake, "being not more than twelve fingers in length," that is so venomous that it leaves a wide trail of deadly venom in its wake, and its gaze is likewise lethal; its weakness is in the odor of the weasel, which, according to Pliny, was thrown into the basilisk's hole, recognizable because all the surrounding shrubs and grass had been scorched by its presence. It is possible that the legend of the basilisk and its association with the weasel in Europe was inspired by accounts of certain species of Asiatic snakes (such as the King Cobra) and their natural predator, the mongoose.
