Westeros: A Game of Thrones.

[Greyblades]

It's completely ridiculous. Roughly 50-100 people knew where the wedding was, and at least half were escorts. With the intrigue level that Renly has, the cunning of Margaery, and the vigilance of Brienne, ya'd think that at least one one of them would have thought something was up when Doran Martell sent Arbor wine to the secret wedding location.

Huh thats wierd, my orders were:

5. Varys will provide a forger and a craftsman who make wax stamps who has less than exepilary morals, Maester Pycell will provide samples every wax seal and letter sent to Robert that he has kept over the years, he should have at least one example from each major lord, and Tywin will aquire a barrel of the finest Dornish wines from Robert's old wine Cellar, I am assuming he'd have left some undrunk. Tywin's own Maester will provide some Strangler crystals.
With all this I will give the Forger some of Doran Martell's and Stannis' letters as examples and order him to make out two letters in each person's handwriting. One from Doran saying the wine is a wedding present, wishing well the marriage etc.
The second will be in Stannis' handwriting giving orders to deliver the wine and Doran's letter to Storm's end with explicit instructions for the bearer not to let anyone drink the wine before it is delivered and that they will be paid twice as much if after delivering the wine and letters they go to Griffin's roost and present Stannis' letter to the lord. While he is doing that I will have the craftsman make stamps that will reproduce the seals of every lord that has sent letters to KL and one blank stamp. With the letters ready Tywin will seal Doran's letter with the copy of Doran's stamp and a wax that can pass off as Dorn's wax, he will seal Stannis' letter with the Blank stamp with black wax.
With that ready he will give the wine and letters to the most loyal Lannister soldier who is not well known enough to be recognised, (i.e. no named character) who will dress in Baratheon colours, go down the road to Storms end and wait at the border for a Trader heading to Storms end, preferably not a local. He will Pass on the wine, the letters, instructions to only open the unmarked letter and a 50 gold advance to get it done. After that I cannot plan but hopefully it will end in Renly or Margery dying at thier wedding.

Maybe that merchant got really lucky.

Sure.piece of cake.

Well maybe easy is a bit of an exaggeration but easier than I would otherwise expect, especially if I had the baratheon troops pretend to be defecting to you and then stab you in the back later.
