Tyrion inspects the Alchemists' Guild supply of wildfire with Hallyne. Hallyne tells him that according to Wisdom Munciter they have 7,840 jars, including 4,000 that date from Aerys II's day. Wisdom Malliard believes that the Guild will be able to provide the full order of 10,000 jars that were promised to Cersei The older jars are particularly fragile from age, however, and should probably have been destroyed, but the guild lost many of its members during the sack of King's Landing and do not have sufficient personnel to do so. A large amount of the stock made for Aerys is still missing, and some still turns up from time to time, including a cache of two hundred jars discovered the year before under the Great Sept of Baelor that no one could recall placing there.1 Tyrion orders several thousand empty jars to be sent to the city watch so they may practice loading the wildfire into catapults without breaking the jars and causing fire in the city. Hallyne thanks Tyrion for his visit, saying that no Hand has graced them with his presence since Lord Rossart, who was a pyromancer himself and appointed because Aerys had a keen interest in the Guild's work. Jaime has told Tyrion that Aerys used his pyromancers to roast his enemies alive.2
Timett is waiting with Tyrion's escort as he emerges from the Guildhall, as is Bronn, who informs him that Ser Jacelyn wants to see him as does Cersei. He goes to see Ser Jacelyn first, who informs him that Ser Cleos has arrived with Robb's peace terms. He sees his cousin and looks over the terms, which are unacceptable. He tells Cleos that he will discuss things with the small council and that Cleos can then return with the king's terms. When Tyrion returns to his chambers, Cersei is waiting for him in a foul mood. Tyrion is not pleased that she got into his chambers unannounced and knows that Crawn will be even less pleased because his Moon Brothers are on guard that day. Cersei is furious that Tyrion has sent Doran Martell an offer betrothing Myrcella to Doran's son Trystane. He plans to send Myrcella to Dorne as a guest, with Ser Arys to serve as her sworn shield, until she turns fourteen, at which point she will marry Trystane. Doran will also get the land, small council seat, and justice that Tyrion told Varys about.3 Tyrion says it is necessary to secure Dorne's support and that Myrcella will likely end up dead otherwise when King's Landing falls. At this point, Cersei does something completely unexpected; she bursts into tears. Tyrion does his best to reassure her that the war is going well, but she is loathe to accept comfort from him. He shows her the peace terms and says it is a good starting point. He is pleased because he knows she will have to accept the offer to Dorne, and he has uncovered an informer.1
