With the news that Roger Ashton-Griffiths has been cast in the role of Mace Tyrell for the upcoming Game of Thrones Season 4, we thought it would be a good idea to give a rundown of what we can expect from this semi-important new character.

First and foremost, Mace is the father of Margaery and Loras Tyrell, and the son of the Queen of Thorns, Olenna Tyrell. He is the acting Lord of Highgarden, and the A Song of Ice and Fire books describe him as being ambitious but lacking savvy and intelligence. He wants to increase the power and influence of the Tyrell family, but doesn’t possess the skills and wit of his mother to make it happen. The TV show will likely portray him in the same light, with the Queen of Thorns already describing him in Season 3 as a “ponderous oaf.”

Now, as for what Mace actually does... well, he doesn’t really do much. However, he is involved in several important plot developments with other characters. Probably his biggest claim to fame for Season 4 will be his role as one of the three judges at the trial of Tyrion Lannister for the murder of King Joffrey. Along with Tywin Lannister and fellow newbie Oberyn Martell, Mace presides over the trial that sees the evidence mount up against poor innocent Tyrion. Of the three judges, Mace is most vocal in his desire to see Tyrion found guilty and put to death, mainly due to the fact that Margaery was also drinking from the cup that poisoned Joffrey.

In later books in the series, Mace becomes more of a thorn in Cersei Lannister’s side due to his constant hunger for power for the Tyrells and his incessant badgering about becoming the King’s Hand. Mace does eventually become Hand of the King to Tommen Baratheon (Joff’s little bro) while Kevan Lannister (Tywin’s little bro) is acting as Regent, but those events are waaayyy into the future for the TV show, if they’re even to be included at all (both Kevan and Tommen have been absent from the show since Season 2).

For now, fans can expect Mace to be another character to give the Lannisters cause to worry about losing their seat of power, and for that we should all be happy.
