There are probably millions of characters in the Game of Thrones series. It is overwhelming at first, but once you get into the novels, or through half of the TV show they all start to become familiar. Arguably the two most important families (sorry Targaryen, Baratheon, Greyjoy, Tyrell, & Martell) of a Song of Ice and Fire are House Lannister and House Stark. These two families alone have over 13 characters, and that is not counting friends and associates. Amazingly, Lego minifigures translate pretty well into the GoT universe. With the recent increase in detail and variety of minifigs, people have many more options when creating their own figures. This version of House Lannister and House Stark has been created by th_squirrel, and is one of the highest quality builds using standard Lego pieces.
First up is House Stark which features, in order from left to right: Sansa, Eddard, Rob, Rickon, Catelyn, Bran, Hodor, Arya, and Jon Snow.
Everyones favorite family to hate, House Lannister, in order from left to right: Tyrion, Jaime, Cersei, Tywin, and Joffery Lannister.
