Fairy Tale Research

"A fairy tale is a type of short story that typically features European folkloric fantasy characters, such as dwarves, elves, fairies, giants, gnomes, goblins, mermaids, trolls or witches and usually magic or enchantments. Fairy tale may be distinguished from other folk narratives such as legends and explicity moral tales, including beast fables."

This selection of research points out that trolls are originally from fairy tales, therefore the two themes shouldn't be too difficult to combine as they both cover the same "fantasy" theme.

"The term is also used to describe something blessed with unusual happiness, as in "fairy tale ending" (a happy ending) or "fairy tale romance" (though not all fairy tales end happily). Colloquially, a fairy tale can also mean any far fetched story or tall tale; it is used especially of any story that not only is not true, but could not possibly be true."

This also points out how the fairy tale theme is unrealistic and unique - couldn't become possible in the realistic world. It also mentions how fairy tales are usually unrealistically happy, so i'm thinking of creating concepts for character with perhaps a positive aesthetic.
