Mace Tyrell

From A Wiki of Ice and Fire

Lord of Highgarden, Defender of the Marches, High Marshal of the Reach, and Warden of the South. Mace Tyrell is a prematurely old and rather tedious man lacking in political savvy. His sole military accomplishment is the Siege of Storm's End. Though he has tried to use the Battle of Ashford as evidence of strategic brilliance, he actually had little to do with the fighting. He now serves only as the figurehead of his powerful house for his more intelligent family members.

Mace has always dreamed of his daughter being a Queen, thus when Renly Baratheon and Loras Tyrell presented the plan to crown Renly and have him wed Margaery Tyrell, they had his full support. However, King Renly’s rule did not last long enough for him to consummate the marriage as he was slain at Storm’s End. When word of this reached Mace, he marched some ten thousand men to Bitterbridge to plan his next move with his sons. They were joined by Petyr Baelish with an offer from King Joffrey Baratheon. Forming an alliance with house Lannister he was soon joined by Tywin's army to march on and defeat Stannis at the Blackwater. His reward was a seat on the small council. Later, he was charged with the capture of Storm’s End, but the siege was interrupted by news that Margaery had been imprisoned. He abandoned his charge and is currently marching his army on the city of King’s Landing.
