Tywin stared down at the Targaryen seal in red wax, he had broken it, yet paused when he saw his wife's feminine, loopy scrawl. She took her personal seal with her everywhere she went, fashioned in the form of a lion ring she wore on her thumb. It was a sign they had agreed to before she left, her writing, but not her words.

Lord Lannister,

On behalf of my brother the King, I am recalling your heir to my side, to answer to the crimes of insult against the crown. You too, shall arrive, to swear fealty to the true King.

Diana La- Targaryen

There was no sweep of signature at the bottom, no proclamation of titles, it was unnerving. Diana loved to include long proclamations at the end of her letters, naming herself Lady of the Westerlands and of Casterly Rock, yet here she used her maiden name as if she were forbidden to call herself anything other than a dragon.

Brandon Stark lunged into Tywin's tent, weeks ride from Harrenhal, still in his riding clothes. Riverrun was a three days ride from here, and it seemed he wasted no time in gathering the host of the Riverlands and marching them here after his wedding. "What is this?" The Stark heir spat, holding a letter with a Direwolf seal. Tywin took the parchment and read it, revealing the same words Tywin was given, only Lord Rickard, it seemed, was demanding Brandon come to swear fealty to the Iron throne, and bring Robert Baratheon to answer for crimes of insult to the crown.

"The King has overstepped," Tywin said flippantly, silently watching Brandon steam as Sandor entered the tent with the Lord's dinner. The entire camp was on edge it seemed, and Tywin had already ordered a thousand Lannister soldiers to march up the gold road, they would intersect them with the forces of the Riverlands and answer the King's request of fealty with a force of their own, and demand the return of Lady Lannister and Lord Stark. "We make demands through his captives, the guard has been sent to the Black Cells, as well as your father." Tywin had spent a good sum of gold for that information, but it was worth every stag. His wife was in the Maidenvault with her sister and daughter, and the information chilled him to the core. Aerys did not think of her as a Lannister, despite the years of their marriage, he saw her as a Valyrian woman.

"I want his head!" Brandon raged, and Sandor snorted at him. "Have something to say, Hound?" The Clegane heir curled his lip at the Stark heir but said nothing else.

"You cannot just decapitate the King of Westeros." Tywin replied, "Not before a trial, that is."

"Like the one Rhaegar was supposed to have?" Brandon bit back, irritating Tywin to no end.

"We ride into the Red Keep tomorrow, Brandon. We must keep an even head." The Lord of Lannister reminded the brute. He poured a glass of Arbour red for each of them. Inside the cask of wine they received was the answer Tywin had been waiting for, the Redwyne fleet had set sail to Stormbreaker Bay, to reinforce the Stormlands while also leaving the Reach vulnerable should they need to attack. Already, Highgarden was pulling their grain stores, preparing supply wagons for battles to come. There was no cry for war, but whispers had caused frantic actions for it.

A/N:

So next chapter jumps back to Diana writing the letter and will lead up to when Tywin reaches the city.
