A Game of Thrones
In the novel, recounting events from various points of view, Martin introduces the plot-lines of the noble houses of Westeros, the Wall, and the Targaryens. The novel has inspired several spin-off works, including several games. It is also the namesake and basis for the first season of "Game of Thrones", an HBO television series that premiered in April 2011. A March 2013 paperback TV tie-in re-edition was also titled "Game of Thrones", excluding the indefinite article "A".
Tyrion Lannister
Seasons 1 and 2 (2011–12) follow the events of "A Game of Thrones" and "A Clash of Kings", respectively. The plot of "A Storm of Swords" was split into seasons 3 and 4 (2013–14). Both season 5 and season 6 adapt material from "A Feast for Crows" and "A Dance with Dragons", novels whose plots run concurrently and each contain different characters. Though the HBO series has alternately extended, abbreviated, conflated and diverged from the novels' plot lines, Tyrion's character and story arc have remained mostly consistent with Martin's writing.
