Goblins, are also sometimes associated with Fairies. (I don't know why this would be other than they are both mean little creatures).
Some say that Goblins are also evil. Their name coming from the Greek kobaloi, which means 'Evil spirit'.
This of course makes perfect sense if you think about the goblins working at Gringotts bank in Harry Potter. How many of those little guys look happy? How many times is Harry betrayed by a goblin? (Actually I can only think of the last movie when he is betrayed but that's beside the point. . . ) :)
And to those I said I would try to do Gargoyles for my 'G' post, I am sorry that did not happen. (I sorta ran out of time and don't have enough information on Gargoyles at the ready to just do a post on them.) So, I promise that in May, I will write a post all about Gargoyles.
