Nymeria was the warrior-queen who led the Rhoynar refugees to Dorne, founding House Martell. Arya Stark named her direwolf Nymeria after this figure. During the War of the Five Kings, Tyrion Lannister planned to marry Myrcella Baratheon to Trystane Martell to strengthen House Lannister's position. Bran Stark, the Three-Eyed Raven, and Jojen Reed are the only ones referred to as Greenseers, who have visions of events past and present. Samwell Tarly was the first character in Game of Thrones to kill both a White Walker and a Thenn.
