Olenna Tyrell POV
Why did she get cursed with an oaf of a son, he is the lord of the most powerful region and army in all of Westeros and what had that got him scorn from the late King Robert for supporting the wrong side during Robert's Rebellion, he was no military commander either claiming the Battle of Ashford as his greatest victory even though he was not involved as his forces were late arriving as usual.
Although a raven had just arrived that could raise their position back to their former glory and she had to make sure that her son did not stuff it up again, she would control him until her Grandson Wilas a great and wise lord in the making took over from his father.
"Let me see the letter Mace " she demanded from her son as she strode into his council chambers where he was having a discussion with his advisors: Randyll Tarly, Matthis Rowan, 2 of his sons Ser Garlan Tyrell and Wilas Tyrell, the Master at Arms Ser Vortimer Crane and Maester Lomys the Maseter for Highgarden.
"Mother it is addressed to me, me and my advisors are busy." replied Mace Tyrel strongly but then regretted it when he saw her angry face, looking up from the desk, his belly almost popping out of his shirt.
"Oh Shut up Mace give it here," she ordered snatching the letter from his hands and reading it. "So do you plan to accept this offer," she asked hoping her son would give her the right answer.
"Of course not, I plan on supporting Roberts's son Joffery he has the strong claim," he replied proudly puffing out his chest.
She looked at the table of advisors and saw they were shaking their heads she knew they had the same thought that she did but Mace could be stubborn wanting glory and power but never actually knowing how to get it always doing the wrong thing.
She sighed putting her hand on her head "Mace you absolute fool, Joffery has no claim did you not read the letter."
"They could be lies," he offered weakly
"Yes but that doesn't matter Renly already has the support of the Stormlands, the North and probably the Tully's, all Joffery has are the Lannisters and maybe the Crownlands whom will probably throw their support to Renly after this news gets out, who else will they ask for help from? Dorne, Prince Doran and Oberyn hate the Lannisters for what they did to Elia, Aegon and Rhaenys. The Greyjoys? They don't ally themselves with anyone and still hate Robert's regime for crushing their rebellion and killing 2 of his sons. Then there is the Vale who as I hear is run by the mad Lady Lysa Tyrell who has isolated her region. Renly also has seized the Myrcella and Tommen baratheon as hostages to control Queen Cersei. So you will drag us into another war on the wrong side outnumbered or will you listen to your mother," she asked sternly
Mace just looked down at his feet not answering.
"You will write a raven back to Renly accepting his offer, your daughter will be Queen, gaining our family more power and position, also in the letter you will ask for a position on the small council, as well one of your lord bannermen, demand that your third son Loras Tyrell gain a position in his kingsguard and propose another marriage between your son Wilas heir to Highgarden and Eddard Starks eldest daughter Sansa Stark strengthening our position," she ordered fiercely turning around in a huff and walking out of the room leaving the men all stunned.
A few hours later she found her granddaughter on one of the highest towers of Highgarden looking out over the river and towers the sea.
"Hello grandmother have you come to convinced me of the greatness of this marriage match," moaned Margaery not turning back to look at her.
"You will be THE Queen Margaery something you have always desired, Loras will be there to protect you," she explained taking Margaery's hand and holding it.
"Yes I know but why him, haven't you heard the rumours about him and Loras, It will be a loveless marriage," her granddaughter retorted
She didn't believe in physical punishment but her fury came out of her as she slapped her granddaughter, "Don't you dare slander our name with talk like that, Yes Renly may be that, but I hear he is caring kind and friendly and anyway he is better than that beast Joffery from what I hear about him."
"I will follow your advice but won't you come with me I could a guide through the politics of King's landing," she appealed obediently.
"Maybe when the war has died down, For now though in a few days you will leave with an advance guard of 2000 men to King's Landing lead by Ser Garlen."
