Petyr Baelish
Hoster Tully is the Lord of Riverrun and Lord Paramount of the Trident. He is the father of Catelyn Stark, Lysa Arryn, and Edmure Tully. He often quarrels with his brother Brynden because Brynden refuses to be married. Years before the events of the series, he agreed to foster Petyr Baelish at Riverrun as a ward. When he discovered that Lysa was pregnant with Petyr's child, he sent Petyr away and tricked Lysa into drinking an abortifacient potion. Hoster supported Robert Baratheon, House Stark, and House Arryn in rebellion against House Targaryen on the condition that Catelyn and Lysa be wed into the Stark and Arryn families, respectively. His health deteriorates rapidly over the novels; he eventually dies and is laid to rest in the river following the Tully tradition.
