I remember being told of the tail & hollow back. And my Great-Grandfather kidded me about “you were born with a troll tail, too! But your Grandmother cut it off!” (Keep all remarks to yourselves, you goddam flying monkeys, you!)
My brother has a huge nose, but not me.
Bridges are so-so. I don’t like goats, & given that one bit me once, I’d say it’s mutual.
I approve of the sport of Dwarf Tossing as good clean fun.
Steel, if sharp & held by a man who wants my wallet, bothers me. Does this count?
I’m going to throw in Icelandic Folk and Fairy Tales as a suggestion; there’s lost of post-Christian stories in there, and I do believe that huldfolk may center around a few stories. I know that there are some stories about the alfar, but Icelanders in the modern days tend to categorize things in “elf” and “troll” categories more than the specifics.
