Troll in the context of "Nordic folklore"

A fairy tale (alternative names include fairytale, fairy story, household tale, magic tale, or wonder tale) is a short story that belongs to the folklore genre. Such stories typically feature magic, enchantments, and mythical or fanciful beings. In most cultures, there is no clear line separating myth from folk or fairy tale; all these together form the literature of preliterate societies. Fairy tales may be distinguished from other folk narratives such as legends (which generally involve belief in the veracity of the events described) and explicit moral tales, including beast fables. Prevalent elements include dragons, dwarfs, elves, fairies, giants, gnomes, goblins, griffins, merfolk, monsters, monarchy, pixies, talking animals, trolls, unicorns, witches, wizards, woodwoses, magic, and enchantments.

In less technical contexts, the term is also used to describe something blessed with unusual happiness, as in "fairy-tale ending" (a happy ending) or "fairy-tale romance". Colloquially, the term "fairy tale" or "fairy story" can also mean any far-fetched story or tall tale; it is used especially to describe any story that not only is not true, but also could not possibly be true. Legends are perceived as real within their culture; fairy tales may merge into legends, where the narrative is perceived both by teller and hearers as being grounded in historical truth. However, unlike legends and epics, fairy tales usually do not contain more than superficial references to religion and to actual places, people, and events; they take place "once upon a time" rather than in actual times.

Hermione Jean Granger (/hɜːrˈmaɪəni ˈɡreɪndʒər/ hur-MY-ə-nee GRAYN-jər) is a fictional character in the Harry Potter series of novels by J. K. Rowling. She first appeared in Harry Potter and the Philosopher's Stone (1997), as a first-year student on her way to Hogwarts. She becomes friends with Harry Potter and Ron Weasley after they save her from a troll in the girls' bathroom. Hermione often uses her quick wit, deft recall, and encyclopaedic knowledge to help her friends in perilous situations. Rowling has stated that Hermione resembles herself as a young girl, sharing similar insecurity and fear of failure.

Hermione has been immensely popular. The version of the character portrayed by Emma Watson in all eight Harry Potter films was voted the best female character of all time in a 2016 poll of Hollywood professionals conducted by The Hollywood Reporter. Arabella Stanton portrays her in the upcoming television series.

A jötunn (also jotun; plural jötnar; in the normalised scholarly spelling of Old Norse, jǫtunn /ˈjɔːtʊn/; or, in Old English, eoten, plural eotenas) is a type of being in Germanic mythology. In Norse mythology, jötnar are often contrasted with gods (the Æsir and Vanir) and with other non-human figures, such as dwarfs and elves, although the groupings are not always mutually exclusive. The entities included in the jötunn category are referred to by several other terms, including risi, þurs (or thurs) and troll if male and gýgr or tröllkona if female. The jötnar typically dwell across boundaries from the gods and humans in lands such as Jötunheimr.

The jötnar are frequently attested throughout the Old Norse records, with eotenas also featuring in the Old English epic poem Beowulf. The usage of the terms is dynamic, with an overall trend that the beings become portrayed as less impressive and more negative as Christianity becomes more influential over time. Although the term "giant" is sometimes used to gloss the word "jötunn" and its apparent synonyms in some translations and academic texts, this is seen as problematic by some scholars as jötnar are not necessarily notably large.

Theodor Severin Kittelsen (27 April 1857 – 21 January 1914) was a Norwegian artist. He is one of the most popular artists in Norway. Kittelsen became famous for his nature paintings, as well as for his illustrations of fairy tales and legends, especially of trolls.

A changeling, also historically referred to as an auf or oaf, is a human-like creature found throughout much of European folklore. According to folklore, a changeling was a substitute left by a supernatural being when kidnapping a human being. Although sometimes it was a "stock" (a piece of wood made magically to resemble the kidnapped human), more often the changeling was a supernatural being made magically to look like the kidnapped human.

Supernatural beings blamed for stealing children included fairies, demons, trolls, nereids and many others. Usually, the kidnapped human was a child; but there were cases, particularly in Scandinavia and Ireland, where adults were taken.
