Daenerys travels to the far flung and exotic city of Asshai by the Shadow, where a fat and greedy merchant feeds her a strange new food called Bur Ito. Dany enjoys the Bur Ito so much that she gives the fat and greedy merchant all three dragons in exchange for the recipe.
She sails to Westeros, where the massed armies of the seven great houses await her. She rides to parlay under a peace flag, and feeds the lords of the seven houses Bur Ito. The lords are overwhelmed with the wonderous new food, and bend the knee, swearing undying fealty to the Lady of Bur Ito, and peace is brought to the Seven Kingdoms.
But the Bur Ito proves to wreck terrible havoc on the digestive systems of the Westerosi, and soon there are murmurings and threats of open rebellion. But by a strange co-incidence, these same digestive problems prove to be a most valuable weapon against the invading horde of wights and Others, after the teenage Rickon Stark discovers that by bending over near a lit torch and eating Bur Ito, he can create a jet of flame twenty feet long.
