Here's the deal with Clegane. It's three black dogs on a yellow background. I had a major case of lazy and made one dog. You want to have two of the dog ABOVE and one of the dog BELOW between the ABOVE dogs. Put some rows of yellow between them and you've got the Clegane sigil. I think you're smart enough to handle that, Internet.
