The Complete Guide to All 21 Major Houses on Game of Thrones

Location: Horn Hill in the Reach
Sigil: A red striding hunstman on a green background
Major members:

• Lord Randyll Tarly, head of House Tarly
• Melessa Tarly, wife of Randyll
• Dickon Tarly, son of Randyll and Melessa and heir to Horn Hill
• Samwell Tarly, son of Randyll and former member of the Night's Watch
• Talla Tarly, sister to Samwell and Dickon

Why They Matter:
Samwell Tarly is the definition of a great friend, which isn't exactly common in a world like Game of Thrones. He's fiercely loyal to the people he cares about, like Gilly, Baby Sam, and Jon Snow. And his plan when he left Castle Black was to study to become a Maester in Oldtown in order to help Jon at the Wall.

Of course, leaving Gilly and Baby Sam safely at his home in Horn Hill didn't exactly work out, and Sam also doesn't know that his BFF is no longer the Lord Commander (or that he had been killed and brought back to life). But no matter what he does next, if Sam's past is any indication, he (and his badass Valyrian sword) shouldn't be counted out.
