Gawen Glover

"Yes. My family served House Stark for centuries. We wept when we heard of your father's death. When my brother was lord of this castle, he answered Robb's call and hailed him "King in the North"! And where was "King" Robb when the ironborn attacked this castle? When they threw my wife and children in prison and brutalized and killed our subjects? Taking up with a foreign whore. Getting himself, and those who followed him, killed. I served House Stark once... but House Stark is dead."

- Robett Glover to Sansa Stark

Gawen Glover is the son of Robett Glover and Sybelle Glover and the brother of Erena Glover. Following the Ironborn capture of Deepwood Motte, he, his mother, and sister are thrown into prison by the Ironborn. Due to King Robb Stark's failure to come to the aid of House Glover, Robett refuses to assist his half-brother Jon Snow and sister Sansa Stark's efforts to retake Winterfell from House Bolton, who had helped them drive out the Ironborn earlier.

Behind the scenes
While Gawen, his mother and sister remain unnamed in the television series, they were briefly mentioned in passing during a conversation between Robett Glover and Sansa Stark in Season 6.

In the books

According to Sybelle, Gawen has just reached his fourth nameday.
