Pledge your allegiance with your very own Game of Thrones House sigil, which you can design and share with your friends!

In a new fun season 3 promotional campaign, HBO is offering fans of Game of Thrones the chance to create their own House and design their banner and sigil!

The banners are highly customizable, allowing you to create very unique designs to represent your family values, your fandom allegiance… or whatever else you might feel like throwing on there.
