shapeshifters and dragons
King Arthur and the round table
My favorite one would be about soulmates. They were one and they were split into two, so they spend their lifetime looking for their soulmate.
I'm kinda fond of the tooth fairy myself...I learned to keep my teeth til I could sleep at Grandma's house....cha ching !!!
Shapeshifters/Vampires and there connections. I love it.
