Not actually featured anywhere in the show, so this is more accurately just an interpretation of house Greyjoy’s sigil from A Song of Ice and Fire. Found the image while searching for examples of the Greyjoy kraken as it appears in HBO’s Game of Thrones and thought the twisty, Celtic-style tentacles were fun. An extraordinarily long, banner-like, HBO version of the kraken is in the works.

I’m not a huge fan of the Greyjoys, but darn it if they don’t have the most interesting sigil in all of Westeros!
