Folklore in The Foster Children of Time

Those of you who have read my book will recall the character Tegwyn's obsession with the Tylwyth Teg, the fairies of Welsh folklore. I did a fair amount of research into fairy folklore and incorporated it into my story. Her insistence that the Tylwyth Teg claim things dropped on the floor was my own invention, however. The idea was that Tegwyn, being an imaginative girl growing up in a world where she takes the existence of magical creatures for granted, has invented her own mythology. This served my own story purposes but also mirrors the way folklore and mythology travels and evolves across societies in real life.
