[X] Plan Fortify
-[X] Eddard will go North and Robb will stay south. The heir to Winterfell has proven himself an adept commander, and it has been too long since its Lord saw his lady wife.
-[X] Send as many scouts and rangers out as possible, in a wide but closely connected net, so that if one disappears or dies, the others know of it. Order them to bring you word of whatever they hear or see. Simultaneously, order for a small host to be gathered near the Long Lake.
-[X] Say nothing in regards to Stannis or Renly. We may have declared for Stannis, but we owe him nothing; he did nothing to aid Lord Eddard in his danger, as should be his duty. Vassalage is a two-way street - if Stannis wants the powers of it, let him prove he also honors its responsibilities. As For Renly, we have no quarrel with him; the Riverlands are ours, and should he want anything of them or us, let him come and ask. But while you do not offer anything to either lords, use this time wisely: fortify, fortify, fortify. Attacks could be coming from all directions. With Baelish in the wind and knowing that Lysa is under his influence, there may come trouble from there. You can't trust the Westerlands to stay silent either for too long. Also, suggest advantageous marriages between Northern and Riverlander noble families to tie the two realms closer together.
-[X] See who has lost the most due to Clegane's rampage and offer that lord to take his head. Before the execution, send out an invitation to Dorne. They can attend the execution if they manage to get there on time and if they want the body afterwards to do whatever they want to do with it, that's fine with us.
-[X] Send a message to all the Lord and Ladies of the Vale regarding the recent occurrences. Express surprise that Lysa did not come aid her siblings,but understanding that she may not have been able to do so. Proclaim Petyr Baelish to be a traitor who killed Jon Arryn and desires to rule the Vale. Hint that Lysa might have been involved in Arryn's death somehow due to her close relationship with Baelish, without outright saying it.
-[X] Negotiate with all the major Northern houses for Robb's betrothal and then chose the one who you need to bind the most to you and offers you most.
-[X] Take up negotiations for Sansa's betrothal with some of the major Vale houses, preferred outcome here being either Harry Hardying or one of the Royces
-[X] It is a bit too early to make commitments for Arya's betrothal. She's young yet and too willful. But keep on the lookout for good marriage prospects advantageous to the war and who could handle Arya. You want her to be happy, after all, and for a second Lyanna Stark not to happen.
-[X] Try to betroth Bran to Lord Lefford's daughter (see below).
-[X] For Theon, speak to the Mormonts and the Manderlys about a possible betrothal to Theon, but don't push. If one of them is inclined to agree, talk to Theon and convince him that you're doing him a favor, wanting him happy, and rediscovering his heritage by giving him strong allies on the coast. Make it seem like he has a choice (he doesn't, of course). Send a letter to Pyke using Theon's progress as a warrior as pretense (talk about all the things that would impress an Ironborn), casually mention that you shattered the Lannisters and that the Westerlands are almost unprotected now, though do not make it seem like you want Balon to attack them. Perhaps if you don't tell them to attack the Westerlands, but give them the information that they're ripe for the picking, they will attack the Westerlands. Also, fortify the North against possible Ironborn attacks, while you are at it, just in case.
-[X] Betroth Bran to Lord Lefford's daughter. Sweeten the deal by having Lady Whent name Bran her heir. Make it so that when they're married, one son will inherit Harrenhal, one son will inherit the Golden Tooth. Meanwhile, Lord Lefford's daughter should be invited as a lady-in-waiting for Catelyn, so that she might meet her betrothed. Have the Blackfish act in Bran's place until Bran is of age, should direct action be necessary in Harrenhal (should Lady Whent die) or in other such cases.
