Ser Davos Seaworth, head of House Seaworth, debuted in the second season of HBO's Game of Thrones adaptation with Liam Cunningham in the role. Cunningham played the role masterfully, portraying the character with integrity and honor. Davos is one of the many point-of-view characters from the Song of Ice and Fire novel series written by George R.R. Martin. Few characters in the series show as much loyalty as Davos.
