Fairies (T)
Tankerabogus
See Knockers.
Trows
These are like the trolls of Scandinavia but they aren't as malicious. They share a fear of the sun and must hide if trapped above-ground during daylight hours.
Tylweth Teg
These are the fairy people of Wales. Mortals might visit Fairyland and even take a fairy bride but time passes on a different scale there and one might emerge to find that centuries have passed. See also Bendith y Mamau.
