Daenerys stands before the House of the Undying, which appears no more than a ruin. Drogon is on her shoulder. Most of those with her, Ser Jorah, Jhogo, Aggo, and Xaro, tell her she should turn back, but she will not. Pyat Pree comes up to take her to the building. As they near the entrance, Pyat gives her some instructions. She must always take the door to her right, and if she comes to any stairs she must go up. She will see visions of the past and future as she climbs, and those that would speak to her from other rooms, but she must keep her path until she reaches the Undying themselves. At the door, a dwarf gives her a glass of shade of the evening to prepare her for the truths within. She enters with Drogon. As she goes through room after room, she begins to see visions through some of the open doors on her left. In one, a woman is being worked over by four men with rat-like faces. In another, she sees a room full of slaughtered corpses at a banquet, with a king with the head of a wolf on a throne.¹ In the next room, Ser Willem beckons her to the house with the red door. Another door near the end of the hall reveals an old man with dark eyes and long, silver-grey hair on a barbed throne proclaiming to a man at the foot: "Let him be king over charred bones and cooked meat. Let him be the king of ashes."² After several more doors, she sees a man that looks like Viserys, but taller and with eyes of a darker purple.³ He turns to a woman nursing a babe and names the child Aegon. The woman asks if he will write a song, and the man replies that "He has a song. He is the prince that was promised, and his is the song of ice and fire." He turns to Daenerys then, and almost seems to see her before adding "There must be one more; the dragon has three heads."⁴

At the end of the hall, Daenerys finds no door on her right and sees the torches going out behind her. She suddenly realizes that the last door on the left is also the first door on the right, and she steps through. After several more rooms, an apparition disguised as Pyat tries to lure her left, but she is not fooled. At the top of a staircase, she opens a door and sees a beautiful room full of people with perfect features. One of them says they are the Undying and bids her to enter. Drogon recoils, and Daenerys realizes there is actually a small door to the right. She flees and enters this one instead. She enters a gloomy room dominated by a long stone table above which floats a human heart, blue and corrupt. A voice hails her as mother of dragons. She can make out the Undying at the table. They are old, wizened, and blue. They appear dead, but just as she thinks that, the voice calls again and says they live. They call her "child of three" and give several foretellings based on that theme. They say she will light three fires: "one for life and one for death and one to love."⁵ They say she will ride three mounts: "one to bed and one to dread and one to love."⁶ Finally, they say that she will know three treasons: "once for blood and once for gold and once for love."⁷ Next, a series of visions come to her faster and faster: Viserys covered in molten gold, her stillborn son Rhaego as a man with a burning city behind him, Rhaegar dying on the Trident, Stannis holding aloft a flaming sword but casting no shadow, a cloth dragon swaying on poles amidst a cheering crowd, a great stone beast taking wing from a smoking tower, Silver riding towards a stream beneath a sea of stars, a corpse with bright eyes and gray lips smiling sadly on the prow of a ship, a blue flower growing in a chink of ice,⁸ Mirri Maz Duur performing her shadow magic, a young Daenerys outside the house with the red door, Mirri Maz Duur dying as Daenerys's dragons hatch, a bloody corpse naked bound and dragged behind Silver, a white lion running through grass taller than a man,⁹ a line of naked crones coming out of a great lake and kneeling before her,¹⁰ ten thousand slaves reaching out to touch her and crying "mother" as she rides past.¹¹ Suddenly, Daenerys realizes that the Undying are all around her touching, clawing, and biting. She cannot move. Drogon belches forth flame and soon the whole room is ablaze. Daenerys runs out of the room and down a long hallway which finally ends in a door leading outside. Pyat Pree is there gibbering in a strange tongue. He lunges with a knife, but Drogon flies at his face. Jhogo and Rakharo subdue him as Ser Jorah comes to Daenerys's aid.
